Manual Metal Arc Welding: Why every weld matters

Every day we cross bridges, hold on to stair railings, lean over balustrades, and rely on the same thing when doing so: support and safety. These properties can only be achieved through flawless, high-quality weld seams produced by qualified manual metal arc welders. We are talking about a professional field in which there is a huge shortage of skilled workers—a problem that is causing concern in the entire industry. But what is actually important when it comes to manual metal arc welding? What can happen in the event of weld defects? And why will this profession always exist despite advancing automation?

“Welder urgently needed” ads are proliferating more than ever before. The shortage of skilled workers has the welding industry firmly in its grip. As ever more members of the older generation retire and take their considerable amount of valuable experience with them, there is a lack of younger welders coming through the ranks to replace them. Manual metal arc welding, which requires skill, expertise, and the highest sense of responsibility on the part of every welder, is particularly affected. If bottlenecks occur here, companies are no longer able to fulfill their orders—especially where automation as a solution is not an option. Firstly, let’s take a look at what the field entails and in which industries manual metal arc welding has become particularly established.

What is Manual Metal Arc Welding and what does it involve?

Manual metal arc welding is a manual joining process that permanently bonds metals together. It includes processes such as MIG/MAG Welding, TIG Welding, and Electrode Welding, and is indispensable in many sectors. Manual metal arc welding is versatile, usually requires little equipment, and impresses with a high degree of mobility. As a result, it has become firmly established in steel construction in particular, but manual metal arc welders are also used on a daily basis for repair welding, pipeline construction, assembly work, or on construction sites.

Automation as a solution for everything (or not)?

Where there is a lack of people, robots will step into the breach—or so you might think. This is indeed the case in many fields, including the welding industry to some extent. Solutions robots mitigate the shortage of skilled workers, allow companies to breathe a sigh of relief, and reduce the strain on workers, especially when it comes to repetitive and tiring work. However, automated processes are reaching their limits when it comes to manual welding, because not every welding task is suitable for robots. Manual welding is advantageous or, in many cases, indispensable, especially with small production runs and for highly specific or complex components.

Manual metal arc welding is also the benchmark where highly individual and flexible welding is required, for example for vehicle repairs or when welding at great heights:

In certain situations and at certain locations, you can only weld by hand. A good example is the construction of highway bridges. Finished sections of roadway are produced elsewhere and delivered to the site, but when the bridge is finally erected, the individual sections are joined together by manual welders. There is also no automated process here, so the responsibility ultimately lies with the individual welding specialists. That is why it is so important not only to continue to have enough manual welders, but above all to have highly qualified ones.

Requirements of Manual metal arc welding
But what makes a good welding specialist? What I need to bring to the table if I want to work in this profession? The fundamentals are the trio of manual dexterity, understanding materials, and resilience. Be it lying under a pipe or kneeling in a narrow container, the working environment is often harsh and hours of welding under difficult conditions can be very physically demanding. Awareness of how you can protect your own health is a fundamental prerequisite for every manual welder: “As a manual welder, you have to pay special attention to your own safety. You are often working for a long time in the most adverse conditions or in the narrowest of spaces, for example in a tank. It is important to ensure proper ventilation and always have a responsible supervisor at your side who checks the safety measures during the welding process.”

Excellent knowledge of materials also plays a key role. “I need to know how heat input and distortion behave during welding, for example, and the joint preparation work must also be carried out properly. What you weld has to last—you have to be able to rely on it”. But how can you be certain about the quality or qualifications of the specialists employed? Welding tests are essential to ensure that the welders are highly trained specialists and that their work is performed properly and professionally. “With their knowledge and experience, manual welders bear an enormous responsibility that cannot be emphasized enough,” emphasizes the welding technology expert.

The highest sense of responsibility for every seam

Where there is a high level of responsibility, mistakes are usually fatal. This also applies to manual welding, because weld defects can have serious consequences. A weld that is not executed properly could crack at some point and lead to material breakage—or, in the worst case, also endanger the safety of people.

I know of a case that happened on a construction site in France a few years ago. A formwork panel fell from a higher floor, directly onto the head of a welder working there. The panel punctured his protective helmet and practically drilled into his head. He was in the intensive care unit for months, fighting for his life. He won the battle, but still lives with a piece of plastic in his head that replaces the part of the skull that was damaged. The cause of this accident was a defective weld, drawing attention to the high level of responsibility as a welding specialist has to bear.

MIG-315L PRO MIG welder and MIG-500PW MIG welder: Effortless manual welding

In addition to skill, sophisticated knowledge of materials, and the highest sense of responsibility, the optimum welding machine is also an important ingredient for successful manual welding. The question here is, what does a good manual welding machine need to be able to do? First and foremost, it must be perfectly matched to the welding task at hand. For example, if welds have to meet the highest standards in terms of both quality and appearance, the MIG-500PW MIG welder is an ideal choice. Visible seams on stainless steel handrails or high-quality pipe connections for swimming pools, as well as precise applications in tank and industrial plant construction, are produced by the MIG-500PW mig mag welding machine with ease.

The MIG-315L PRO MIG welder is a reliable companion when welding has to be carried out under the most adverse conditions. On the outside, the durable machine keeps environmental factors like dust and moisture at bay, while the pioneering technology offers a range of convenient functions to facilitate the welding process. At just 22 kg, the Ignis is lightweight, but still very robust. Welders can therefore count on the powerful manual welding machine both indoors and outdoors, in rain or sunshine, at great heights, or in the tightest of spaces.

Be it MIG-315L PRO, MIG-500PW, or another high-quality welding machine, the key is to choose a machine that is perfectly designed to meet the needs of both welders and the task at hand—and on which the specialists can rely on day in, day out. But no matter the manual welding task, the responsibility does not lie with the machine, but rather in the hands of each and every individual welding specialist. After all, despite all the technical progress and automation we have seen, it is people who remain indispensable in many places.

MIG Welding vs. MAG Welding – Is There a Difference?

Both MIG and MAG welding fall under the common name “gas metal arc welding” or GMAW.

However, MIG (metal inert gas welding) and MAG (metal active gas welding) have one significant difference — the type of used shielding gas.

In this article, we’ll examine the difference between the MIG and MAG welding processes and explain what each is meant for.

Getting Started with Welding: A Welding Guide for Beginner’s

How GMAW Works in Short

Gas metal arc welding (both MIG and MAG) joins metal by using a consumable electrode (solid wire) under the protection of a shielding gas.

The solid metal wire is pushed via an automated wire feeder through the MIG gun and energized via a power source. Small, portable, inverter-based MIG welders usually combine a wire feeder and a power source into one unit — the MIG welding machine.

For example, our MIG-200DP mig welder supports the MIG welding process because it has a wire feeder inside the unit, and an inverter-based power source that provides the necessary voltage and welding power in the wire.

200A MIG-200 4-in-1 Multi-Process MIG Welders

GMAW works by short-circuiting electricity released from the welding machine. The ground clamp is attached to the positive terminal, while the MIG gun is negative. So, once you grip the welded material with the ground clamp and the positive wire (coming from the MIG gun) touches the metal, the electrical short occurs, melting the wire and a piece of the welding joint. Metal melts due to internal resistance to the flow of electrons in the circuit.

gas metal arc welding

As the wire melts away, it deposits a metal droplet into the joint. Then, the wire feeder pushes more wire to short with the metal, and this process keeps repeating many times per second. This gives GMAW its characteristic sizzling sound and causes the spatter. Every time the wire shorts with the grounded metal, the sparks and spatter fly around because shorting works like a small explosion.

This is why the most common GMAW metal transfer method is called “short circuit metal transfer.” There are also other GMAW transfer methods like spray, globular, and pulse transfer. But, these are more advanced and out of this article scope. You can read about Pulsed MIG welding here if you want to learn more.

MIG – Metal Inert Gas Welding Process

MIG welding uses inert welding gas to shield the weld puddle from atmospheric contamination. Inert gasses like argon and helium don’t chemically interact with the molten metal, so they don’t influence the weld to a large extent.

You need to use 100% argon to weld non ferrous materials like aluminum, magnesium, copper, and nickel or its alloys. But, you cannot use 100% argon gas to weld ferrous metals like steel. We’ll talk about this soon when we get to the MAG welding.

MIG Welding vs. MAG Welding - Is There a Difference

MIG Welding vs. MAG Welding – Is There a Difference

Argon gas produces a favorable atmosphere in the weld puddle that’s very easy to ionize, so keeping a long arc with lower voltage is relatively easy.

Helium can be added to argon to increase arc heat, puddle fluidity, and weld penetration. You can also use 100% helium if welding very thick sections of aluminum or magnesium, but this will reduce arc stability.

MAG – Metal Active Gas Welding Process

MAG welding uses active gas or a combination of active and inert gasses. Active or reactive gasses directly influence the weld penetration, puddle fluidity, arc stability, weld spatter, and the resulting bead.

The two most commonly used reactive shielding gasses for MAG welding are oxygen (“O2”) and carbon dioxide (“CO2”). Oxygen is only used as an addition to argon, while it’s possible to weld with 100% CO2.

Custom gas mix

You cannot efficiently weld steel with 100% argon because the uneven iron oxides on the steel surface emit electrons that attract the arc in unpredictable directions. As a result, the weld deposits are irregular, and it becomes challenging to create a uniform weld.

Mixing oxygen with argon creates a reaction on the steel surface that results in a uniform iron oxide surface. This provides a stable path for the arc to follow and allows you to lay beautiful welds.

However, it’s rare for regular folks to use oxygen and argon bland. Carbon dioxide provides an excellent substitute for oxygen.

You’ve probably heard about an argon and carbon dioxide blend numerous times because 75% argon and 25% CO2 is the most common shielding gas employed in GMAW.

Adding carbon dioxide to argon creates a more favorable weld bead and a deeper penetration. Plus, the arc is more stable if using argon/CO2 than argon/O2.

However, you should use a MIG welding wire that contains deoxidizers to prevent reactive gasses like oxygen and carbon dioxide from causing porosity.

Speaking of which, MAG welding with a pure CO2 gas produces very deep weld penetration, but it does cause more spatter and produces slightly less appealing welds compared to the 75/25 mixture discussed earlier. If you have enough skills to weld with a very short arc, you can mitigate the increased spatter. Just make sure you use a wire designed for welding with 100% CO2.

Conclusion

While most people use MAG welding more often than MIG welding, almost everyone calls both processes MIG welding. While this is technically incorrect, it has become somewhat of a norm in the industry to refer to all GMAW processes as MIG welding.

This causes little to no harm in everyday welding work. So, most people just stick to MIG welding as their go-to name for the process. Since there isn’t a significant apparent difference, and most professionals know exactly which shielding gas to use with every metal, using the MIG welding term for both MIG and MAG is deemed acceptable.

It’s not like a certified welder would use straight argon to weld steel if someone would ask them to MIG weld it. Instead, they’d know to use either straight carbon dioxide or a mixture with argon, which is technically MAG welding.

How to Compare and Choose Between MIG Welding and TIG Welding?

There are many best methods to fuse metals by welding through various methods. Among many options are MIG and TIG — MIG stands for Metal Inert Gas and Tungsten Inert Gas. The debate over which method is the best-doing rounds for quite some time now. Each method has its benefits, given the nature of the work/project.

To compare the two, let us help you understand MIG welding and TIG welding. We will additionally look into their differences and ultimately choose which is better.

What is MIG?

Metal Inert Gas welding or MIG welding is the popular and easy welding process. A consumable wire electrode is needed to create an electrical arc between the item being welded and the consumable wire doing the welding. The metal rod is used as an electrode and also as a filling material.

Once the metal heats up and the welding process begins, the welding gun releases inert gas from the gas nozzle to keep the contaminants away. The gas is the combination of CO2 and Argon.

MIG Welding Components –

Power — The source is mainly DC with a steady voltage.
Wire
Electrode
Torch
Conduit
Filler metal
Gas shielding

TIG Welding

Tungsten Inert Gas welding or TIG welding is named because of the tungsten electrode inside the welding. Since the tungsten doesn’t readily melt, it conducts the electricity arc directly to the components you need to fuse. In other words, the wire is held by the operator that is touched to the electrode to melt into the base item.

TIG welding, or Tungsten Inert Gas welding, is very similar to MIG welding. TIG still relies on a wire to feed and heat up to melt the base item and wire to form the weld.

TIG Welding Components –

Power — The source can be AC or DC.
Torch
Foot pedal -This controls the electricity that goes to the torch.
Electrode and gas shielding
Filler material –
Backing bars: These help cool the weld area faster than on its own.

Applications of MIG & TIG Welding

MIG Welding

There are various MIG welding applications, and before that, one has to gauge how a particular welding process fits the project. For instance, when working on thicker metals, the filler used in MIG welding will firmly hold the parts.

MIG welding is versatile and can be used on a wide variety of projects as long as the welder matches the gas and wire to the types of metal he/she needs to conjoin.

Here are some of the examples of MIG applications:

Metal component repairs
Automotive repairs and manufacturing
Trailer hitches
Farming equipment
Construction welding
Pipe welding
Underwater welding projects
Railroad track repair
Shipbuilding

TIG Welding

For a work that requires precision, TIG welding is the top choice. It can be used on various metals (steel, bronze, nickel, brass, copper, gold, etc.), which is why the process is applied in diverse industries, helping create and repair many items.

This welding process is known for its strength and precision.

Here are some of the examples of industries that use TIG welding –

Aircrafts & Spaceships
Automobile
Industrial fixtures
Metal sculptures

Which one is better — MIG or TIG?

Although the process may seem similar, some differences set the processes apart. For instance, MIG uses a consumable wire, whereas TIG uses a tungsten electrode that isn’t consumable.

Now, each welding process has its usage that best fits them; that is where the difference lies. If you want speed over accuracy, MIG is for you, and if you choose the latter, TIG can give you the best results. TIG welding is more suitable for thinner metals, and MIG welds work well with extensive projects with thick metals.

Your better understanding of the MIG and TIG welding process will help you make an informed choice when working on the project.

A Beginner’s Guide for MIG Welding: Understanding MIG Welders

MIG welding, also known as Gas Metal Arc Welding (GMAW), is a widely used welding technique that has revolutionized the world of metal fabrication. This process is known for its versatility, speed, and efficiency, making it a popular choice for a wide range of applications, from automotive repair to industrial fabrication. Whether you are a seasoned welder or just starting out, MIG welding provides a simple and effective method to join metal parts together. In this guide, we will explore the basics of MIG welding and provide you with the tools you need to get started on your welding journey. From understanding the principles of MIG welding to choosing the right equipment and practicing proper safety techniques, you’ll gain the knowledge and confidence you need to tackle your next welding project with ease.

I. Definition of MIG Welding

MIG welding is an arc welding process that uses a continuous wire feed to join two metal parts together. The process involves a wire that is continuously fed through a gun, which melts the wire and creates a weld bead on the workpiece. Shielding gas is used to protect the weld from oxidation and other forms of contamination, ensuring a clean and strong weld. MIG welding is a versatile process that can be used on a wide range of metal materials, including steel, aluminum and stainless steel, making it a popular choice for many industrial and manufacturing applications.

A. How MIG Welding Works

MIG welding works by using an electric arc to heat the metal parts being joined, causing the metal to melt and fuse together. A MIG welder provides a constant feed of welding wire through a gun to the weld joint. When the gun is triggered, an electrical arc is established between the tip of the welding wire and the metal workpiece, creating heat that melts the wire and the metal at the joint.

The shielding gas, typically a mixture of Argon and CO2, is directed towards the weld joint to protect the molten metal from oxidation and other forms of contamination. As the welding wire is continuously fed into the arc, the metal solidifies and creates a strong bond between the two parts being joined. The operator controls the speed of the wire feed and the position of the gun, allowing for precise control over the size and shape of the weld bead.

MIG welding provides a simple and efficient way to join metal parts together, with the added benefits of a clean, consistent weld bead and minimal cleanup required. With proper training and practice, MIG welding can be an effective and reliable welding method for a wide range of applications.

B. Comparison to Other Welding Techniques

MIG welding is just one of several welding techniques available, and it’s often compared to other welding methods such as TIG welding, Stick welding, and Flux-Cored Arc Welding (FCAW). Here is a comparison of MIG welding to these other welding techniques:

🔸TIG Welding: TIG welding is a similar process to MIG welding, but it uses a tungsten electrode instead of a welding wire. TIG welding is typically used for thin materials and precision welding applications, where the operator has more control over the heat and welding speed. However, TIG welding is often slower and requires more skill than MIG welding.

🔸Stick Welding: Stick welding, also known as Shielded Metal Arc Welding (SMAW), is another welding method that uses an electrode and an arc to join metal parts. Stick welding is typically used for outdoor or heavy-duty welding applications, where a more rugged and durable weld is required. However, stick welding can produce a lot of slag, which must be removed after the weld is complete.

🔸Flux-Cored Arc Welding (FCAW): FCAW is similar to MIG welding, but it uses a flux-cored wire instead of a solid wire. FCAW is typically used for heavy-duty welding applications and is often faster than MIG welding. However, FCAW can produce more fumes and spatter than MIG welding, and the flux residue must be cleaned up after the weld is complete.

Each welding technique has its own unique set of benefits and drawbacks. MIG welding is a fast, efficient, and versatile process that is well-suited for many applications. However, the choice of which welding technique to use will depend on the specific requirements of each project, such as the thickness of the metal, the desired speed and precision, and the type of weld required.

II. Choosing the Right MIG Welder

Choosing the right MIG welder can be a challenge, as there are many factors to consider and a wide range of options available on the market. Here are some key factors to consider when choosing a MIG welder:

⭐️Power Requirements: Consider the power requirements of your welding projects, and choose a MIG welder that matches your needs. MIG welders are available in a range of power capacities, from 110V models for home use to industrial-grade models that require a 3-phase power supply.

⭐️Duty Cycle: The duty cycle of a MIG welder refers to the amount of time that the welder can be used continuously before it needs to cool down. Consider the size of your welding projects and the amount of continuous use you’ll need to determine the right duty cycle for your needs.

⭐️Welding Wire Type and Size: MIG welders are designed to use a specific range of welding wire types and sizes. Consider the thickness of the metal parts you’ll be welding and the type of metal you’ll be using to choose a MIG welder that is compatible with your needs.

⭐️Features and Accessories: Consider the features and accessories that you need, such as adjustable welding speed, wire feed control, and spool gun compatibility. Consider the type of welding projects you’ll be undertaking and choose a MIG welder that offers the features and accessories that you need.

⭐️Budget: MIG welders are available at a wide range of price points, from budget-friendly models for hobbyists to high-end models for professional use. Consider your budget and choose a MIG welder that fits your needs and budget.

III. Setting Up Your MIG Welder

Once you have chosen the right MIG welder for your needs, it’s time to set it up and get started with your welding projects. Here are some steps to help you set up your MIG welder:

⭐️Choose the Right Power Source: Make sure that you have access to the right power source for your MIG welder. If you’re using a 110V model, you’ll need access to a standard household electrical outlet. If you’re using a higher-powered model, you’ll need access to a 240V or 3-phase power source.

⭐️Set Up the Welding Machine: Mount the welding machine securely to a sturdy workbench or stand, and connect the power cable and ground cable. Connect the gas cylinder to the welder, and turn on the gas to start the flow.

⭐️Choose the Right Welding Wire: Choose the right welding wire for your project based on the thickness of the metal and the type of metal you’ll be welding. Make sure that the wire is compatible with your MIG welder, and load it into the welder’s spool.

⭐️Set the Welding Parameters: Set the welding parameters, such as the welding speed, wire feed speed, and voltage, to match the requirements of your project. Consult the manufacturer’s instructions for specific guidelines, and make any necessary adjustments.

⭐️Test the Welder: Before you start welding, perform a test run to make sure that everything is working properly. Make any necessary adjustments to the welding parameters, and make sure that the weld is consistent and of good quality.

VI. Basic MIG Welding Techniques

Once you have set up your MIG welder and are familiar with the basics of MIG welding, you’re ready to start welding. Here are some basic MIG welding techniques to help you get started:

◾️Push or Drag Technique: The push or drag technique refers to the direction in which you feed the welding wire into the joint. In the push technique, you feed the welding wire into the joint from the same side as the shielding gas, while in the drag technique, you feed the wire from the opposite side. Choose the technique that is best suited to your project and welding conditions.

◾️Travel Speed: The travel speed is the speed at which you move the welding torch along the joint. Maintaining a consistent travel speed is important to ensure a smooth and even weld bead.

◾️Welding Angle: The welding angle is the angle at which you hold the welding torch relative to the joint. A 45-degree angle is a good starting point, but you may need to adjust the angle to suit your project and welding conditions.

◾️Welding Position: The welding position refers to the orientation of the joint and the welding torch. MIG welding can be performed in a variety of positions, including flat, vertical, overhead, and horizontal. Choose the position that is best suited to your project and welding conditions.

◾️Weld Bead Profile: The weld bead profile refers to the shape of the weld bead. A concave profile is desirable for most welding applications, as it provides good penetration and a strong weld.

V. MIG Welding Safety

Welding can be a dangerous activity, so it’s important to take safety precautions and follow best practices to protect yourself and others. Here are some key safety considerations for MIG welding:

1. Wear Personal Protective Equipment: Wear protective clothing, including a welding helmet, gloves, and protective sleeves, to protect your skin and eyes from sparks and hot metal.

2. Ensure Adequate Ventilation: Welding produces fumes and gases that can be hazardous if inhaled. Make sure that the welding area is well-ventilated and use a fume extractor if necessary.

3. Avoid Welding in Confined Spaces: Welding in confined spaces can be dangerous, as the fumes and gases produced can accumulate and pose a hazard. If you must weld in a confined space, make sure that you have adequate ventilation and take appropriate safety measures.

4. Use Ground Clamps: Attach ground clamps to the workpiece to ensure that you have a safe electrical connection and to reduce the risk of electrical shock.

5. Keep Welding Cables and Hoses Clear: Make sure that welding cables and hoses are clear of any obstacles, including sharp edges and hot metal, to prevent damage and reduce the risk of tripping.

6. Store Welding Equipment Safely: Store welding equipment safely, away from flammable materials, to reduce the risk of fire.

In conclusion, MIG welding is a versatile and widely used welding technique that offers numerous benefits over other welding methods. Whether you’re a beginner or an experienced welder, MIG welding can help you achieve your welding goals with speed, efficiency, and accuracy. With a basic understanding of MIG welding principles, an appreciation for the importance of safety, and some practice and experience, you’ll be able to master MIG welding and tackle a wide range of welding projects with confidence and success. Whether you’re welding for personal projects, for your business, or as a professional welder, MIG welding offers a wealth of opportunities and possibilities, and it is sure to be an invaluable tool in your welding arsenal for years to come.

Mig Welding Aluminum with a Spoolmate 30A Spool Gun

For Mig Welding aluminum…..You most often need a spool gun.

In this video, you can see that when mig welding aluminum, the weld puddle is pushed and not pulled. You can also notice the cleaning action of the arc around the edges of the weld puddle that breaks up the aluminum oxide and allows the puddle to wet in to the base metal. There are several aluminum mig welding techniques that work ok, but the one used in the video is just a slow steady motion.

For 1/8″ thick aluminum, unless you have the machine set just right, the slow steady bead just builds up too much heat because by the time you reach the edge of the metal, its really too hot and leaves a huge crater.

Another thing to learn from this video about aluminum mig welding is that it uses what is known as “spray transfer”.

Can you See the tip of the wire? It never goes into the puddle. Fine little droplets of metal “spray” into the weld. When you mig weld steel with “short circuit transfer” the wire actually fuses into the puddle and then arcs back many times a second and makes that bacon frying sound.

You do not want to hear a bacon frying sound when mig welding aluminum. IF you do, you have too much wire speed.

Another technique that I like better is to use kind of a step and pause technique where you hitch ahead quickly about a quarter inch and then pause…to the tune of about once every second.

So it goes like this. move ahead and pause…thousand one…move ahead and pause…thousand two.. This step and pause welding technique puts ripples in the weld like a tig weld. Almost like a stack of dimes. Another benefit is it seems to build up less heat by moving quicker.

The picture below is of a weld that was done using a step and pause welding technique with the spool gun.

The best way I have found to figure out the voltage and wire feed speed settings is to go to powerwelds.com and use their weld calculator .

Select process, material type and thickness. For 1/8″ thick aluminum, the lowest recommended setting for 3/64″ wire was 21 volts and 240 inches per minute.

That will only get you started and it is a good starting point…since every machine is a little bit different, tweaking the machine while playing with some scrap aluminum will get you even better results.

More Tips for Spool Gun Mig Aluminum Welding

“spool guns make me feel powerful!.. “

Aluminum wire is much softer than steel and is hard to feed very far thru a liner. That is the reason for spool guns. With a spool gun, the wire only has toe fed for a few inches. Whereas with a conventional mig setup, the liner is usually about 8-10 feet long. Trying to push soft aluminum wire thru a cable that long is challenging and mostly just not doable. The spool gun is the way to go. 1 pound spools of aluminum wire are loaded into a small gun that resembles a Tommy gun gun from old gangster movies. The spool gun is slightly less maneuverable than a conventional mig gun but the trade off is worth it in being able to consistently feed aluminum wire without bird nesting every few minutes.

100 % argon gas is usually the gas of choice but mixtures like 50/50 argon/helium can be helpful for welding thick sections.Make sure the polarity is connected properly. mig welding aluminum requires reverse polarity. Another way of saying reverse polarity is Direct current electrode positive or DCEP. The same polarity is used for welding steel with bare wire but since mig machines can be used for self shielded flux core wire also and some of those wires require using DCEN or Straight polarity, It is a good idea to check the polarity setup just to be sure.

The 1 pound spools shown in this welding video are available in either 4043 or 5356 alloy and other alloys too, but these 2 are the most commonly used. 5356 is a bit stiffer and is easier to feed. It is commonly used for mig welding 5052 aluminum. But the 4043 wets out better and generally gets less porosity. 5356 is also slightly stronger.

There are lots of considerations when choosing and there is a filler metal chart you can download at this link….. That has some valuable tips for choosing welding wire.

In the second video, the suggestion for setting wire tension is excellent. Trying to weld with not enough wire tension will cause burn backs and lots of cursing. Set the tension tight enough but not too tight. Too tight and the drive rollers will mash the wire and cause other problems.

Some important tips for mig welding aluminum:

1. Push dont pull. Pushing works much better whenever you can… But we both know that sometimes you just gotta do what you gotta do. Pulling the weld will cause it to be sooty but its not the end of the world. A stainless brush will remove the soot.

2. when setting the wire feed speed, start out high and then adjust lower. You will save lots of tips this way, trust me on this.

3. dont try to get the bacon frying sound like with steel, if you are getting this sound, your wire feed is a little to high. you are looking for a high pitched humm.

4. always snip the wire in between welding. this will save many tips

5. keep the stickout to around 3/4″ and you will save many tips

6. keep a new pack of tips in your toolbox cause… damn! – mig welding aluminum , even on a good day , goes thru some tips.

It is possible to mig weld aluminum without a spool gun. I used to work in a shop that did this. A short mig cable, a teflon liner, and a softer tension spring allowed us to weld pretty well. The trick was to angle the mig gun to that about an inch of wire fed out before it contacted the weld area. Then you could change to a normal welding angle. If we didnt do this, we got a lot of burnbacks because the mig machine did not have any run out or wire feed delay features.

Choosing the Best Welder For Home Use—Buying Guide

It can be confusing when it comes to choosing the best welder for home use as there are a lot of specifications to sieve through, and special terminology that not all will be familiar with, especially those who are not professional welders.

This brief guide will look at some of the important things to consider when buying a welder.

TIG Welding/MIG Welding

MIG (metal inert gas) welding and TIG welding are welding processes that both require the use of gas to work. MIG welders are usually preferred by hobbyists or DIYers as MIG welding is one of the easiest welding processes to learn.

TIG welding on the other hand requires a little more skill but it produces the cleanest welds. Both MIG and TIG welding do not produce slag which is another plus to consider with both welding processes.

Flux Cored Arc Welding/Stick Welding

Stick welders and flux core welders, on the other hand, do not require gas to run and therefore produce slag during the welding process.

Stick welding is popular as it is fast and cheaper to run, however, the welding takes a little getting used to as an arc has to be maintained while the rod is burning. Flux-cored welding is slightly easier but is suitable mainly for ferrous metals and is not great for thinner metals.
