7.15 MIG Timer PCB (PCB2) Test

Using the MAIN PCB terminal JB-5 as common measure the voltage at JD-1. This should measure 20VDC when the
Gun Switch is closed. Then measure the voltage at JD-2.

WELD MODE SELECTOR WITCH

POSITION

VOLTAGE AT JD-2

2T

10VDC when Gun Switch closed. Drops
0VDC when Gun Switch is released.

SPOT

10VDC for duration of SPOT TIME then
3.3VDC.
Drops to 0VDC when Gun Switch is
released.

STITCH

10 VDC for durations of STICH TIME.
3.3VDC for durations of DWELL TIME.
Drops to 0VDC when Gun Switch is
released.

4T

14VDC at 1

st

Gun Switch closure

Drops to 0VDC at second Gun Switch
closure.

If the voltages are not found to be correct, replace PCB2.

To confirm the rest of the circuitry is working, Disconnect JC connector from Main PCB and place a jumper between
JD-1 to JD-2. When the Gun Switch is closed: (This test disables the Timer functions and will only function as if in the
2T WELD MODE)

Gas Flows

Contactor energizes

Feed Roll turns

Display reads output voltage
