Stainless Steel
Air Plasma / Air Secondary
General purpose cutting
Plasma @ 60 psi (4.1 bar)
Secondary @ 60 psi (4.1 bar)
Nitrogen Plasma / Air Secondary
High quality, low cost operation
Plasma @ 60 psi (4.1 bar)
Secondary @ 60 psi (4.1 bar)
NOTES:
1. Kerf widths are listed as the width of the cut at the bottom of the plate.
2. Speed, kerf width, voltage and standoff data represent realistic starting points. Adjustments may be
required to obtain optimum results.
3. The copper shield cup (9-5790) is recommended for general machine cutting. When the clear-the-plate
function of a height control is required, then the short copper shield cup (9-5801) is recommended.
4. Nitrogen plasma with CO2 secondary may be used. CO2 flowrate is 240 scfh, which requires six 50 lb
cylinders manifolded together or a bulk CO2 system. Shop compressed air is a good alternative if pro-
viding the required CO2 flowrate is not feasible.
