3.05 Input Power Cable
Connections
WARNING
Disconnect primary power at the source before con-
necting the primary power cable to the power sup-
ply.
The primary input power cable (see CAUTION) is sup-
plied and must be connected by the user to the primary
power source. Power Supply is factory wired for 380-
415 VAV, three-phase power.
CAUTION
The primary input power cable must not be modi-
fied in any way as shielding is installed on the cable.
The power source must conform to local and national elec-
tric codes. Recommended circuit protection and wiring
requirements are shown in Appendix 1.
Connect the primary input power cable to the customer power
source as follows:
1. At the free end of the input power cable, cut back
the insulation on the individual wires approxi-
mately 1/8 - 3/16 inch (3 - 5 mm).
2. Connect the ends of the individual wires to a customer
supplied plug as follows:
NOTE
All the input cable wires must be connected for
three-phase operation.
• Blue wire to Line 2 (Live)
• Black wire to Line 3 (Live), refer to Note
above
• Brown wire to Line 1 (Live)
• Green/Yellow wire to Ground (Power
Ground)
• Input Cable Shield Connector to Ground
(Power Ground)
NOTE
Refer to subsection 3.08 for procedures on install-
ing an earth ground for the power supply and work
cable.
3.06 Gas Connections
The Power Supply provides the liquid cooling and gases
to support operation of the Torch.
NOTE
Refer to the Automated Torch Instruction Manual
for information on plasma and secondary gas se-
lection and requirements.
The following gases can be used with this System:
• Plasma Gases
Compressed Air, Nitrogen, Argon/Hydrogen
• Secondary Gases
Compressed Air, Carbon Dioxide (CO2), Nitrogen
Gas requirements vary depending on the application. The
gases are connected to the rear panel connections of the
power supply. The source of the gases will determine
the gas connections required.
This sub-section includes information for connecting the
gas supplies to the Power Supply. The information is
grouped in paragraphs for different types of gases and
options as follows:
A. Using Shop Air Only
B. Using Plasma Shop Air and Secondary High
Pressure Gas Cylinder
C. Using High Pressure Gas Cylinders Only
A. Using Shop Air Only
NOTE
The Two Stage Air Line Filter Assembly is to be
used when using shop air as the Plasma Gas.
An inline pneumatic dryer/evaporator type air filter, ca-
pable of filtering particulates to at least 5 microns with a
dew point of 35°F (1.7°C), is required when using air from
a compressor. This type filter will insure that moisture,
oil, dirt, chips, rust particles, and other contminants from
the supply hose do not enter the torch. For highly auto-
mated applications, a refrigerated drier plus a particu-
late filter may be used to chill the air to remove all mois-
ture.
CAUTION
When using shop air, the air supply must be free of
oil, moisture, and other contaminants. Excessive
oil and moisture may cause double-arcing, rapid
tip wear, or even complete torch failure. Contami-
nants may cause poor cutting performance and
rapid electrode wear.
