4.02 Preparations for Operation
At the start of each operating session:
WARNING
Disconnect primary power at the source be-
fore assembling or disassembling power sup-
ply, torch parts, or torch and leads assemblies.
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 volt-
age. Make sure the input power source meets
the power requirements for the unit per Section
2, Specifications.
2. Connect the input power cable (or close the
main disconnect switch) to supply power to the
system.
Air Source
Ensure source meets requirements (refer to
Section
2). Check connections and turn air supply ON.
Connect Work Cable
Clamp the work cable to the workpiece or cutting
table. The area must be free from oil, paint and rust.

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 cool-
ing fans turn ON.

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 ex-
ists and for a ten (10) minute period once the
condition is cleared.
Set Operating Pressure
1. Place the Power Supply Function Control knob
to 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 details.
