This gas combination gives good cut speed, low dross levels and is very economical. Some surface nitriding can
occur.
Notes: Set plasma gas inlet pressure to 90 psi (6.2 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
Production cutting above 1" (25 mm) not recommended
Drop cutting above 1-1/2" (38 mm) not recommended
