200 amps • Air Plasma / Air Shield
This gas combination gives good cut speed, low dross and is very economical. Some surface nitriding and surface
oxidation of alloying elements can occur.
Notes: Set air plasma gas inlet pressure to 90 psi (6.2 bar)
Set air shield gas inlet pressure to 90 psi (6.2 bar)
Production cutting above 7/8" (22 mm) not recommended
