This gas combination is used when surface nitriting and surface oxidation of alloying elements is less
important. Electrode life is extended when using this gas combination.
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 7/8 inch (21 mm) not recommended.
