INTRODUCTION & DESCRIPTION 10 Manual 0-2557
9. Plasma Gas Requirements
a. Plasma Gas
Compressed Air, Oxygen (O2), Nitrogen (N2),
or Argon/Hydrogen(ArH2)
b. Pressure
60 psi (3.4 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)
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.
10. Secondary Gas Requirements
a. Secondary Gas
Compressed Air, Carbon Dioxide (CO2), or Ni-
trogen (N2)
b. Pressure
60 psi (3.4 bar)
CAUTION
Maximum input gas pressure must not exceed 125
psi (8.6 BAR)
c. Flow
Cutting or Gouging: 220 scfh (103 lpm)
CAUTION
Secondary water source only for use in machine
applications (refer to Power Base Unit Operating
Manual 0-2474).
11. Secondary Water Requirements

B. Torch Leads Extension
NOTE
The following applies to the Torch Leads Exten-
sion used in the TD-750 System only.
Part of the TD-750 Systems to interface the Power Base
Module to the Arc Starter Box. Supplied in 50 ft (15.2
m) length. Accessories available to extend the Arc
Starter Box from the Power Base Module up to 100 ft
(30.5 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).
• Phenolic (plastic) Pinch Block Mounting Assembly
For machine mounted torch applications where a
non-metal mounting assembly is desired.
• Multi-Gas Conversion Kits
Converts dual gas air/air systems to multi-gas op-
eration. The multi-gas systems can use oxygen, ni-
trogen, or argon/hydrogen as the plasma gas. The
kits include regulators, supply hoses, and spare
parts kit.
