TROUBLESHOOTING WELDING
PROBLEMS
RECOMMENDED ACTION
Machine will not turn on
Check cords and wiring in the plug. Check circuit
breaker.
Machine runs, but will not weld
in either mode. Red LED is on.
Check for sound work clamp connection. Make
sure work/Torch cable is securely fastened to
DINSE connector. Reset main power switch if
overcurrent light is on after cool down period.
Contact Technical Support.
Arc has difficulty establishing,
welding rod sticking
Wet welding rods. Too low of amperage. Too
high of amperage. Use fresh rods. Adjust amps.
Wrong polarity
Welding rod is rapidly consumed.
Too small of welding rod. Too high of amperage
setting. Wrong polarity.
Discolored weld color. Too
much spatter. Additional TIG
symptom: Tungsten is discolored
Stick: Too long of arc length. Too high of amps.
TIG: Same as above/ Low flow rate of shielding
gas. Too short of post flow period. Wrong TIG
cup size.
Weld quality is poor, unstable
arc. Weld is dirty/oxidized.
Clean paint/rust from weld. Make sure work
clamp has good contact. Too low of amps/Too large
of tungsten. Incorrect wiring of welder. Tungsten
(TIG) is poorly ground/contaminated
LED illuminates yellow/green or
red. Machine runs, but no weld
power.
Duty cycle exceeded. Allow machine to cool.
Reset main power switch after full cool down
period. Make sure fan is not blocked. Overcurrent
(red). Check circuits for over/under voltage.
Dirty power from generator. Internal fault
Slight whine or squeal to arc or
to welder while turned on.
This is normal and the sounds may vary.
Circuit breaker trips. Internal
Fuse blown.
Wiring fault. Too small of a wire or circuit breaker.
