This gas combination is used when cut edge quality and surface nitriting are less important. Electrode life
is extended when this combination is used.
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.
* Production cutting above 1 inch (25 mm) not recommended.
