4.02 Preparations for Operation

At the start of each operating session:
WARNING
Disconnect primary power at the
source before assembling or disas-
sembling power supply, 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 (100 amps maximum). Refer to
Section 4T.07 and following for torch parts selection.
Torch Connection
Check that the torch is properly connected. Only
ESAB model SL100 / Manual or SL100 / Mechani-
cal 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

Power ON
Place the Power Supply ON / OFF switch to the ON
(up) position.
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
operation 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 condi-
tion 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
1. Place the Power Supply Function Control knob
to the SET position.
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.
OPERATION
AC indicator turns ON.
Gas will flow.
