Plasma / Air Shield
This gas combination gives superior cut speed, minimum dross, minimum amount of surface nitriting and
excellent weldability.
Set plasma gas inlet pressure to 120 psi (8.3 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
If leads are greater than 50 feet, increase TEST pressure 5 psi for every extra 50 feet of torch lead length.
