BASIC MIG (GMAW) WELDING TROUBLESHOOTING
FAULT CAUSE REMEDY
1 Undercut A Welding arc voltage too high
B Incorrect gun angle
C Excessive heat input
A Decrease voltage or increase the Wire Feed Speed.
B Adjust angle.
C Increase the gun travel speed and/or decrease welding
current by decreasing the voltage or decreasing the
Wire Feed Speed.
2 Lack of penetration A Welding current too low
B Joint preparation too narrow or gap
too tight
C Incorrect shielding gas
A Increase welding current by increasing Wire Feed
Speed and increasing voltage.
B Increase joint angle or gap.
C Change to a gas which gives higher penetration.
3 Lack of fusion Voltage too low Increase voltage.
4 Excessive spatter A Voltage too high
B Voltage too low
A Decrease voltage or increase the Wire Feed Speed
control.
B Increase the voltage or decrease Wire Feed Speed.
5 Irregular weld shape A Incorrect voltage and current settings.
Convex, voltage too low. Concave,
voltage too high.
B Wire is wandering.
C Incorrect shielding gas
D Insucient or excessive heat input
A Adjust voltage and current by adjusting the voltage
control and the Wire Feed Speed control.
B Replace contact tip.
C Check shielding gas.
D Adjust the Wire Feed Speed control or the voltage
control.
6 Weld cracking A Weld beads too small
B Weld penetration narrow and deep
C Excessive weld stresses
D Excessive voltage
E Cooling rate too fast
A Decrease travel speed.
B Reduce current and voltage and increase MIG Gun trav-
el speed or select a lower penetration shielding gas.
C Increase weld metal strength or revise design.
D Decrease voltage.
E Slow the cooling rate by preheating part to be welded
or cool slowly.
7 Cold weld puddle A Loose welding cable connection.
B Low primary voltage
C Fault in power source
A Check all welding cable connections.
B Contact supply authority.
C Have an Accredited CIGWELD Service Provider to test
then replace the faulty component.
8 Arc does not have a
crisp sound that short
arc exhibits when the
Wire Feed Speed and
voltage are adjusted
correctly.
The MIG Gun has been connected to
the wrong voltage polarity on the front
panel.
Connect the MIG Gun to the positive (+) welding terminal
for most solid wires and gas shielded ux cored wires.
Connect MIG Gun to the negative (-) welding terminal
for most Gasless Wires. Refer to the electrode wire
manufacturer for the correct polarity.
