This gas combination is used when surface nitriding and surface oxidation of alloying elements is less important.
Electrode life is extended when using this gas combination.
Notes:
Set nitrogen plasma gas inlet pressure to 120 psi (8.3 bar)
Set carbon dioxide shield gas inlet pressure to 90 psi (6.2 bar)
Production cutting above 7/8" (22 mm) not recommended
