5.01 Basic Troubleshooting-Power Source Faults
NOTE!
In the table below, words "Faulty Power PCB, Control PCB or Display PCB" will appear, refer to relative sec-
tions to detect and confirm the fault.
Refer to Section 5.06, 5.08, 5.09 and 5.10/Item 1/Power PCB to detect whether the Power PCB is defective.
Refer to Section 5.07, 5.10/Item 4/Control PCB and 5.11 to detect whether the Control PCB is defective.
Refer to Section 5.10/Item 3/ Display PCB to detect whether the Display PCB is defective..
If Power PCB, Control PCB or Display PCB is broken, replace accordingly.
Fault
Possible Cause
Remedy
1
There is no weld output and
all front panel displays are off
A
B
C
D
E
F
G
The main Power Switch is set to OFF
Line fuse is blown
The main Power Switch is faulty
Loose connection
Faulty Power PCB
Faulty Control PCB
Faulty Display PCB
A
B
C
D
E
F
G
Set main Power Switch to ON
Replace Line fuse
Replace main Power Switch
Tighten connections
Replace Power PCB
Replace Control PCB
Replace Display PCB
2
There is no weld output and
all front panel displays are off
or flickering on & off
A
The internal protection circuit to shut the
unit down if the mains supply voltage is
too high has operated
A
Check to see if mains supply voltage
is <274VAC. A generator with poor
voltage regulation may cause a
supply voltage in excess of 274VAC.
Connect Power Source to a supply
voltage <274VAC.
3
There is no weld output and
the yellow over temperature
light is on
A
B
C
Unit has overheated
Airflow inlet or outlet ducts are blocked
Fan does not operate
A
B
C
Allow unit to cool with fan running
until over temperature light
extinguishes
Remove blockages from airflow
ducts
Replace fan. Check fan wiring header
is plugged securely into Control PCB.
Check fan wiring for damage.
4
Mode switch does not change
welding mode
A
Faulty Display PCB
A
Replace Display PCB
5
The wirefeed motor and the
weld output do not operate
when the torch trigger switch
is depressed
A
B
C
D
E
F
G
H
Internal wiring fault
Over temperature light is on
Power Source set to REMOTE
Trigger wires shorted to weld voltage
inside torch
Trigger wires or torch switch faulty
Faulty Power PCB
Faulty Control PCB
Faulty Display PCB
A
B
C
D
E
F
G
H
Check continuity of internal wiring
from Torch adaptor through to boards
Allow unit to cool
Set switch to LOCAL
Repair trigger wires in torch
Check & Repair
Replace Power PCB
Replace Control PCB
Replace Display PCB
