Plasma / Air Shield
This gas combination gives superior cut speed, minimum dross, minimum surface nitriding and excellent
weldability.
Notes:
Set oxygen plasma gas inlet pressure to 120 psi (8.3 bar).
Set nitrogen 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.
Drop cutting above 1-1/2" (38 mm) not recommended
