Plasma / Air Shield
This gas combination gives good cut speed, low dross 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).
Notes:
Set oxygen plasma gas inlet pressure to 120 psi (8.3 bar)
Set nitrogen plasma gas inlet pressure to 120 psi (8.3 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
Production cutting above 3/8" (10 mm) not recommended
* To maximize consumable life, modify the part lead-in and lead-out to reduce ramp-down errors.
For strip cutting or other applications where proper ramp-down is difficult to achieve, use electrode P/N 120667 in
place of electrode P/N120547.
