INTRODUCTION 2-2 Manual 0-2554
4. Cutting Range
Most materials up to 2 inch (50.8 mm)
Up to 3/4 inch (19 mm) for production speed cutting
5. Pierce Rating
3/4 inch (19 mm)
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), Ni-
trogen (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. Hot Flow
Cutting: 22 - 28 scfh (10.4 - 13.2 lpm)
Gouging: 22 - 43 scfh (10.4 - 20.3 lpm)
scfh = standard cubic feet/hour
NOTE
Hot flow is measured with the main arc activated.
When pressure is set correctly the plasma gas flow
rate is significantly higher until the arc is initi-
ated.
9. Secondary Gas Requirements
a. Secondary Gas: Compressed Air, Carbon Diox-
ide (CO2), or Nitrogen (N2)
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. Flow - Cutting or Gouging: 220 scfh (103 lpm)
scfh = standard cubic feet/hour
10. Secondary Water Requirements
a. Water Source (See Notes): Clean drinking qual-
ity tap water can be used as a secondary
b. Water Pressure: Minimum 50 psi (3.5 bar)
c. Water Flow: Cutting: 6 gph (35.2 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)
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).
• Phenolic (plastic) Pinch Block Mounting Assembly
For machine mounted torch applications where a non-
metal mounting assembly is desired.
• Torch Leads Extension
The leads extension is part of the system to extend
the Torch from the Power Supply. Accessories are
available to extend the Torch from the Power Supply
up to 100 ft (30.5 m).
• Spare Parts Kits
Kits contain replacement front-end torch parts and
tools. Spare parts kits are available for air, oxygen
(O2), nitrogen (N2), and argon-hydrogen (Ar/H2)
cutting.
