BASIC TROUBLESHOOTING
Problem
Causes
Remedy
There is output current when pulling the torch
trigger, gas feeding but there is no wire feeding out.
1.
The wire feeder is clogged.
2.
The wire feeder has failed.
3.
The control PCB or wire feeding
power PCB inside the machine has
failed.
1.
Unclog it.
2.
Repair / replace it.
3.
Replace it.
When the torch trigger is pulled, there is gas
output, but there is no output current,
1.
The earth cable is not well connected
with the workpiece.
2.
The wire feeder has failed.
3.
The welding torch has failed.
1.
Adjust / re-connect
clamp.
2.
Repair the wire feeder.
3.
Repair or replace the
welding torch.
There is no response when pulling the torch trigger
.
1.
The welding torch is not properly
connected with the wire feeder.
2.
The torch trigger fails.
1.
Remove and re-connect
torch.
2.
Repair or replace the
welding torch.
The welding current is unstable.
1.
The pressure arm on the wire feeder
is not properly adjusted
2.
The drive roll does not match the
wire size being used.
3.
The contact tip of the welding torch is
badly worn.
4.
The wire-feeding tube of the welding
torch is badly worn.
5.
The electrode is of poor quality.
1.
Adjust it to get proper
pressure setting.
2.
Make sure the wire and roll
size is a match.
3.
Replace it.
4.
Replace it.
5.
Change electrode supply.
The overheating LED is on
.
1.
The overheating protection circuit
has reached its limit and shut down
the machine.
1.
Ensure the welding machine is
in an open area able to receive
sufficient air flow.
2.
Ensure the fan is functioning.
3.
Disconnect power source and
inspect if the inside of the
machine is filled with dust –
clean / blow out machine as
necessary.
The torch becomes very hot while welding.
1.
Welding torch rating is too low.
2.
The torch liner is badly worn or
damaged causing the wire to “drag”
3.
Welding area is in tight closed space not
allowing air flow for cooling.
1.
Replace torch with larger
higher rated torch.
2.
Replace torch liner.
3.
Take frequent stop “breaks” to
allow the torch too cool down
or install equipment to direct
fresh airflow to welding area at
contact.
The electrode holder becomes very hot during welding.
1.
T
he rated current of the electrode
holder is smaller than its actual working
current.
1.
Replace the electrode holder
with a higher rated one.
