Troubleshooting Guide
Fault Cause Remedy
1. The AC power indicator light is
not lit and welding arc can not
be established.
1. No power input or main power
switches damage.
2. Indicator damage.
1. Check input power or replace
main power switch.
2. Replace indicator light.
2. The AC power indicator light on
and welding arc can not be
established.
1. Input voltage unstable.
2. Diode damage. 1. Connect stabilizer or reset power
switch.
2. Replace diode.
3. The warning indicator light on. Over load. Reduce current or wait moment.
a. No gas flow
No wire feed
No output
1. MIG torch plug is not insert into
the socket or the connect is
bad.
2. MIG torch damage (diagnose
method: make the welding
machine control socket two
pins short circuit, the faulty
disappear).
3. Wire feeder plug is not insert
into the socket or the connect
condition is bad.
1. Insert the plug correctly, and
rotate it clockwise.
2. Repair or replace MIG torch.
3. Insert the plug correctly, and
rotate it clockwise.
b. No gas flow
Have wire feed
Have output

4. Repair or replace.
5. Replace
6. Replace
8. The maximum output welding
current can not achieved in the
rated input voltage. Main board damage. Repair or replace.
9. The current decrease in the
weld process.
Faulty cable connected to work
piece. Make sure the cable positive connect
to the work piece correctly.
