At the start of each operating session:
WARNING
Disconnect primary power at the source
before assembling or disassembling power
supply, torch parts, or torch and leads as-
semblies.
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
4T.07 and following for torch parts selection.
Torch Connection
Check that the torch is properly connected. Only
Thermal Dynamics model SL100 / Manual or SL100 /
Mechanical Torches may be connected to this Power
Supply. See Section 3T of this manual.
Check Primary Input Power Source
1. Check the power source for proper input voltage.
Make sure the input power source meets the power
requirements for the unit per Section 2, Specifica-
tions.
2. Connect the input power cable (or close the main
disconnect switch) to supply power to the system.
Air Source

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 sufficient 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
an over temperature condition occurs, the
fans will continue to run while the condition
exists and for a ten (10) minute period once
the condition is cleared.
Set Operating Pressure

the SET position. Gas will flow.
2. For Standoff cutting, adjust gas pressure from 70 - 85
psi / 4.8 - 5.9 bar (LED's in center of control panel).
Refer to the Standoff chart for pressure setting de-
tails.
