3. Optional HF and NO-HF to fulfill market requirements.
4. Narrow cutting seam, clean cutting edge, anti-deformation.
5. Overheat, overcurrent, and overvoltage protection.
6. Accurate cutting current preset ensures good cutting effect, energy-saving performance, and convenient operations, suitable for cutting workpieces of different thicknesses.
7. Adjustable pre-flow checking and post-flow cooling.
How to Select Your Plasma Cutter Air Compressor?
Pressure is the force of the compressed air being fed to your plasma cutter. The value for gas pressure may be represented in pounds per square inch (psi), megapascal (MPa) or bar.
Air compressor system pressure is preset and usually between 100 psi and 135 psi. Output pressure is adjustable via the pressure regulator. Inlet pressures vary by system. For a small handheld plasma cutter running at 20-30 amps, you’ll need as little as 80 psi (5.5 bar). Larger, automated plasma cutting systems in the 130 to 800 amp range may require 115 psi (8 bar) or more.
