This gas combination may be used when cut edge quality and surface nitriding are less important. Electrode life is
extended when using this combination.
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 1" (25 mm) not recommended
