Torch Parts Selection
Check the torch for proper assembly and appropriate
torch parts. The torch parts must correspond with the
type of operation, and with the amperage output of this
Power Supply (120 amps maximum). Refer to Section

Power ON
Place the Power Supply ON / OFF switch to the ON (up)
position. AC indicator turns ON. Gas indicator
turns ON if there is sucient gas pressure for power
supply operation and the cooling fans turn ON.
NOTE!
Minimum pressure for power supply op-
eration is lower than minimum for torch
operation.
The cooling fans will turn ON as soon as the
unit is turned ON. After the unit is idle for
ten (10) minutes the fans will turn OFF. The
fans will come back ON as soon as the torch
switch (Start Signal) is activated or if the
unit is turned OFF, then turned ON again. If

fans will continue to run while the condition
exists and for a ten (10) minute period once
the condition is cleared.
