Description
1. The welding arc cannot be established.
2. The welding arc cannot be established
when the Fault Indicator is on
3. Maximum output Welding Amperage
cannot be achieved with nominal Input
Supply Voltage.
4. Welding Amperage reduces when weld-
ing.
5. Circuit breaker (or fuse) trips during
welding.
6. Difficult to establish an arc in Stick
mode.
7. The arc wanders away from the joint
during welding (Arc Blow).
8. Wire feeds out of MIG Gun but no shield-
ing gas flows.

TROUBLESHOOTING and MAINTENANCE
Electric shock Electrostatic dis-
can kill charge can damage
PC Boards
Possible Cause
A The Input Supply Voltage isn't switched
ON.
B The Power Source switch is switched
OFF.
C Loose connections internally.
D No Open Circuit Voltage in Stick or Lift
TIG mode.
A The Power Sources duty cycle has been
exceeded or a fault has occurred.
B Internal component failure.
C Fan not working.
Defective control circuit
Poor work lead connection to the work piece. Ensure that the work lead has a positive electrical
The circuit breaker (or fuse) is under size.
A Loose connections in welding leads.
B Metal is contaminated with oil or rust or
grease or dirt.
A Air movement is pushing the arc.
B The coating on the stick electrode isn't
even around the metal core.
C Welding Amperage passing thru the metal
sets up a magnetic field which pushes the
arc.
A Gas cylinder empty.
B Gas regulator closed.
C Faulty solenoid or electronics.
D Restriction in MIG Gun cable.

Remove any metal- Flying metal or
lic particles / dirt dirt can injure
using vacuum eyes
cleaner
Remedy
A Switch ON the Input Supply Voltage.
B Switch ON the Power Source.
C Have an approved Service Provider repair the
connection. Refer to SECTION 7 – PRO-TEC
WARRANTY POLICY.
D Have an approved Service Provider inspect
then repair. Refer to SECTION 7 – PRO-TEC
WARRANTY POLICY.
A Wait for the Indicator to go out then reduce
welding time or get approved Service Provider
to repair. Refer to SECTION 7 – PRO-TEC
WARRANTY POLICY.
B If Fault indicator does not go out after 10
minutes then have an approved Service Pro-
vider inspect then repair the welder. Refer to
SECTION 7 – PRO-TEC WARRANTY POLICY.
C If fan is clogged with dust then remove dust.
If fan does not rotate then have an approved
Service Provider inspect then repair the weld-
er. Refer to SECTION 7 – PRO-TEC WARRAN-
TY POLICY.
Have an approved Service Provider inspect then

WARRANTY POLICY.
connection to the work piece.
Refer to Section 4.6 and Section 4.7 for the rec-
ommended circuit breaker (or fuse) size for the
Input Supply Voltage used.
A Check all welding leads electrical connections
for defects like burnt or discoloration connec-
tions. Replace/replace electrical connections
or welding leads.
B Clean metal to remove contamination.
A Shield the weld zone from the air movement.
B Use a new electrode from another batch.
C Reposition the Earth Clamp position to reduce
this affect.
A Change to a full gas cylinder.
B Open gas regulator.
C Have an approved Service Provider repair the
connection. Refer to SECTION 7 – PRO-TEC
WARRANTY POLICY.
D Straighten out MIG Gun cable.
