9.Trouble shooting
TROUBLE (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF
ACTION
1. When machine
energized, the circuit
breaker trip
Three phase bridge rectifier was may
damage
Replace the rectifier
；
IGBT damage Replace IGBT
2. No output current
The control fuse on the back may
broken
Replace fuse 1.5A
Cooling fan not work, or overload
cause overheat, then temperature
relay protect
Repair the cooling fan and do not
overload
Temperature relay may damage Replace the temperature relay
3. Arc strike can’t success
Machine output terminal not connect
reliably with the work piece
Reliably connect the work piece
and output terminal
Torch trigger or plug wire may
damage
Replace the torch trigger and well
connect the plug
4. There is no output
voltage, but noise
from the machine
FRD may damage Replace the FRD
5. Difficult to strike arc
Workpiece too dirty Clean the workpiece
Tungsten quality not good Replace good tungsten
6. Cannot turn off the
argon gas.
PW03 damage
；
Replace PW03
；
There are substance in gas valve
；
Clean the air valve

the overload indicator
on Machine overload
Stop welding, let the machine rest
for 10min without load
Cooling fan damage Replace cooling fan
10. Arc break during
welding or the machine
not work, but the lack
voltage indicator on
Water pressure too low or no water let
in Connect water
The water checking switch damage Replace the water checking switch
11. When use water
cooling torch, machine
not
work, but the
cooling water indicator
on
The input lack-phase or lack voltage Check three phase input
