SECTION 4

4.2 SEQUENCE OF OPERATION

Prior to performing the steps below, open the wall disconnect switch or remove the fuse from the fuse box to electrically
isolate the power source.
WARNING
4.2.1 General Procedures for the CV-MIG (GMAW), SUB ARC (SAW) and CC-STICK (SMAW), SUB
ARC (SAW) Processes
A. Make the secondary output connections to the positive and negative output receptacles. See paragraph 3.4 and
figure 3-5.
B. Make the control connections. Refer to the appropriate wire feeder, mechanized control, and/or torch instruction
booklets for additional process requirements or control connections.
C. If primary input connections have been made to the power switch, and on the input terminal board to match the
incoming voltage, close the main wall disconnect switch or reinstall fuses in the fuse box.
4.2.2 Specific Procedures for the CV-MIG (GMAW) and SUB ARC (SAW) Processes
A. Set the Output Panel/Remote switch to the desired setting.
B. Set the Process switch to the CV position.
C. Set the contactor switch to "Remote".
WARNING
D. Set the power switch on the rear panel to the "on" ("I") position. The fan will run for 30 seconds and stop automati-
cally if welding current does not exceed 100 amps. The fan will automatically turn off after 6 minutes when the
contactor is "off" and the welding current is below 100 amps.
E. To preset the approximate welding voltage, place the Contactor switch to the "on" position. This will energize the
power source output, allowing the voltage to be preset using the Output Voltage/Current Control dial and observ-
ing the voltmeter.
ELECTRIC SHOCK CAN KILL! "MACHINERY LOCKOUT PROCEDURES"
SHOULD BE EMPLOYED. IF IT IS NOT POSSIBLE TO USE PADLOCKS,
ATTACH A RED TAG TO THE LINE DISCONNECT SWITCH OR FUSE BOX
WARNING OTHERS THAT THE CIRCUIT IS BEING WORKED ON.
ELECTRIC SHOCK CAN KILL! WHEN THE CONTACTOR SWITCH IS IN
THE "ON" POSITION, OUTPUT POWER WILL BE PRESENT THROUGH
OUT THE WELDING CIRCUIT; ie. CABLES, WIRE FEEDER, WIRE SPOOL,
DRIVE STAND, GUN, AND ELECTRODE. BE SURE ALL ARE CLEAR OF
THE WORKPIECE OR ARCING WILL RESULT.
