Air Plasma / Air Shield
This gas combination gives good cut speed, low dross levels and is very economical.
Set plasma gas inlet pressure to 90 psi (6.2 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.
* Production cutting above 1/8 inch (3 mm) not recommended.
