4. Cutting Range
• Production speed cutting:
3/4 inch (19 mm) at 150A
1 inch (25.4 mm) at 300A
• Maximum capacity when edge starting:
2 inch (50.8 mm)
5. Pierce Rating
3/4 inch (19 mm) at 150A
1 inch (25.4 mm) at 300A
6. Transfer Distance
3/8 inch (10 mm)
7. Torch Parts
Gas Distributor, Electrode, Tip, Shield Cup Body,
End Cap
8. Plasma Gas Requirements
a. Plasma Gas: Compressed Air, Oxygen (O2),
Nitrogen (N2), or Argon/Hydrogen (Ar/H2)
b. Pressure: 65 to 75 psi (4.5 to 5.2 bar)
CAUTION
Maximum input gas pressure must not exceed 125
psi (8.6 bar)
c. Cold Flow
Cutting: 65 to 75 scfh (30.7 to 35.4 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 Di-
oxide (CO
2
) or Nitrogen (N2)
b. Pressure: 65 to 85 psi (4.5 to 5.9 bar)
CAUTION
Maximum input gas pressure must not exceed 125
psi (8.6 bar)
c. Flow: Cutting: 220 scfh (103 lpm)
scfh = standard cubic feet per hour
10. Secondary Water Requirements
a. Water Source (See Notes): Clean drinking
quality tap water can be used as a secondary
b. Water Pressure: Minimum 50 psi (3.5 bar)
c. Water Flow: Cutting: 6 - 8 gph (35 - 47 lph)
NOTES
Tap water should only be used as a secondary on
machine torches.
The tap water source does not need to be deionized,
but in water systems with extremely high mineral
content a water softener is recommended.
Tap water with high levels of particulate matter
must be filtered.
11. Weight (without leads)
1.0 lb (0.45 kg)
B. Torch Supply Leads
The following applies to the Torch Supply Leads only:
The Torch Supply Leads are made up of individual hoses
and cables. The Torch Supply Leads are part of the sys-
tem to interface the Master Power Supply to the Arc
Starter Box. The Torch Supply Leads are available to ex-
tend the Arc Starter Box from the Power Supply up to
125 ft (38.1 m).
2.04 Options And Accessories
These items can be used to customize a standard system
for a particular application or to further enhance perfor-
mance (refer to Section 6 for ordering information).
• Spare Parts Kits
Kits contain replacement front-end torch parts and
tools. Spare parts kits are available for air, oxygen
(O2), and multi-gas cutting.
