Mild Steel
100* amps • Air Plasma / Air Shield
This gas combination gives good cut speed, low dross levels and is very economical. Some surface nitriding can
occur. While this process may be used on thicker materials, optimal recommended range is to 3/8" (10mm).
*
Set arc current to
80 amps
when cutting .075" (2 mm) thick mild steel
Notes:
Set plasma gas inlet pressure to 90 psi (6.2 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
Production cutting above 3/8" (10 mm) not recommended
