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