ting

8. Plasma Gas Requirements
a. Plasma Gas: Compressed Air, Oxygen (O
2
), Ni-
trogen (N2), or Argon/Hydrogen(ArH2)
b. Pressure: 75 to 100 psi (4.8 to 6.9 bar)
CAUTION
Maximum input gas pressure must not exceed 125
psi (8.6 bar)
c. Cold Flow
Cutting: 60 - 90 scfh (28.3 - 42.5 lpm)
scfh = standard cubic feet per hour
NOTE
Cold flow is measured before the main arc is acti-
vated. When pressure is set correctly the plasma
gas flow rate is significantly lower when the arc is
initiated.
9. Secondary Gas Requirements
a. Secondary Gas: Compressed Air, Carbon Diox-
ide (CO
2
), or Nitrogen (N2)
b. Pressure: 15 to 60 psi (1.0 to 4.1 bar)
CAUTION
Maximum input gas pressure must not exceed 125
psi (8.6 bar)
c. Flow
Cutting or Gouging: 15 to 220 scfh (7 to 103 lpm)
scfh = standard cubic feet per hour
10. Secondary Water Requirements
a. Water Source : Tap Water
b. Water Pressure: Min. 50 psi (3.5 bar)
c. Water Flow : Cutting: 6 - 8 gph (35 - 47 lph)
11. Weight (without leads)
1.0 lb (.45 kg)
