Plasma / Air Shield
This gas combination gives good cut speed, low dross level, and is very economical. Some surface
nitriting can occur. While this process may be used on thicker materials, optimal recommended range is to
3/8 inch (10 mm).
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 3/8 inch (10 mm) not recommended.
