Plasma / Air Shield
This gas combination is used when cut edge quality, surface nitriding and surface oxidation of alloying elements
are less important. Electrode life is extended when this combination is used.
Notes: Set nitrogen plasma gas inlet pressure to 120 psi (8.3 bar)
Set air shield gas inlet pressure to 90 psi (6.2 bar)
Production cutting above 7/8" (22 mm) not recommended
