Power Supply Output Connections
Perform the following steps to connect the output of the power supply to the torch
leads and the work table. See Figure 3-2 for additional information.
Note: When making hose connections, only tighten the brass
fittings enough to make a gas seal. The fittings are
subject to damage if over tightened.
Torch Leads
1.
Remove the threaded ring from the brass shield connector on the end of the
braided shield.
1
2.
Route the torch leads through the opening in the rear of the power supply and
push the shield connector through the hole until it is seated against the sheet
metal.
3.
Slide the threaded ring over the torch leads and thread onto the shield
connector.
Tighten the threaded ring firmly.
The shield connector grounds
the braided shield to the power supply enclosure to help eliminate high
frequency noise emission. Using an ohmmeter, measure zero ohms between
the braided shield and the ground stud on the sub-panel inside the power
supply.
4.
Connect the torch electrode lead (3/8” hose) to the Torch Electrode fitting on
the I/O board.
5.
Connect the torch nozzle lead (3/16” hose) to the Torch Nozzle fitting on the
I/O board.
Work Ground Lead
1.
Route one end of the #4 AWG work ground lead through the bushing on the
lower rear of the power supply and connect it to the Work Ground connection
on the I/O board.
2
2.
Connect the other end of the work ground lead to the star ground point on the
cutting table. The star ground point is generally referred to as the common
ground point on the cutting table where all subsystems of the machine are
grounded. This point is then connected to a driven earth ground rod that
should be as close as possible to the star ground. The ground rod should have
no other wires connected to it. The ground rod should be at least 3/4 inches in
diameter and should be driven into the earth’s permanent moisture layer. The
length of the ground rod varies from installation to installation and should be
installed according to local and national codes. Refer to the National
Electrical Code, Article 250, Section H, Ground Electrode System for
additional information.
