3. Defective MIG GUN / SPOOL GUN SELECTOR
SWITCH SW2
a. Check continuity of SW2.
4. Defective WIRE FEED MOTOR M2
a. With Gun Switch closed, measure for approx
2-16 VDC variation at the control PCB between
JB-6 to JB-8 as the WIRE SPEED CONTROL
potentiometer is varied from minimum to
maximum. If voltage is correct, replace motor.
5. Open wire from Rectifier assembly to Control PCB
a. With gun switch closed, measure for approx
27 VDC at Control PCB between JB7 (-) to JB9
(+). If no voltage, check wire continuity and
replace open wire.
6. Faulty MAIN PCB
a. With gun switch closed, measure voltage
between JB-6(-) to JB-8 (+) for approx 10 VDC.
If voltage is 0 VDC, replace Control PCB.
7. Defective FINE or COARSE VOLTAGE CONTROL
SWITCH.
a. See VOLTAGE CONTROL SWITCH test
procedure, page 7-11.
8. Defective Rectifier assembly
a) Check per the diode test procedure page 7.16.
9. Defective Main transformer
a. Check main transformer per test procedure
page 7.17.
7.10 Spool Gun Control (J1) Problem
A. Gas does not flow when jumper is connected
between J11 Pins D & G
1. Defective gas solenoid SOL2
a. Measure for 32VAC at SOL2 between Orange
wires (# 31C) and Violet wire (#58). If voltage
is correct replace SOL2. For all other issues
regarding J11 check SW2.
7.11 Output Voltage Problem
A. Output is low in one or more OUTPUT VOLTAGE
CONTROL SWITCH positions
1. Defective OUTPUT VOLTAGE SELECTION SWITCH
a. Check continuity of switch. See test procedure
on page 7-11.
2. Defective MAIN TRANSFORMER
a. Check Main transformer per test procedure on
page 7-14.
7.12 Wire Feed and Weld Problems
A. Poor or inconsistent arc transfer or no arc transfer
1. Poor work cable connection or open work cable
a. Clean contact point, check continuity of cable
and cable to clamp connection. Replace if work
cable if required.
B. Wire feed and welding problems
(Refer to sections 6.03 & 6.03 )
