Welder does not “hum”
when turned on.
No power at electrical outlet. 1.
Broken or damaged Power Cord. 2.
Check circuit fuse or circuit breaker. 1.
Have Power Cord repaired or replaced by 2.
a qualified electrician.
Welder “hums” but does
not weld.
Inadequate current at electrode and/or poor 1.
connections at Welder.
Check Ground Clamp, Cable, and 1.
connection to workpiece.
Check Welding Cable and Electrode
2.
Holder.
Check all Welder external connections.
3.
Arc difficult to strike. Electrode diameter too large. 1.
Workpiece not properly grounded. 2.
Heavy loads, making power line voltage low. 3.
Use smaller diameter electrode. 1.
Verify proper grounding (no paint, varnish, 2.
or corrosion).
Run Arc Welder on dedicated 230 volt
3.
circuit.
Welder gives trickle shots. Accidental contact with workpiece. 1.
Current leakage caused by moist clothing or 2.
work area.
Avoid contact with workpiece. 1.
Make sure clothing and work area are dry. 2.
Welder overheats, blows
fuses, trips circuit breaker.
Use of extension cord. 1.
Electrode diameter too large. 2.
Overloaded circuit. 3.
Relocate Arc Welder to avoid use of 1.
extension cord. If relocation of Welder
is not possible, use thicker (lower gauge
number) extension cord.
Use smaller diameter electrode.
2.
Run Arc Welder on dedicated 230 volt 3.
circuit.
Bead is intermittently too
thin or too thick.
Inconsistent travel speed. 1.
Output Amp setting too low. 2.
Decrease and maintain travel speed. 1.
Increase output Amp setting or change to 2.
smaller diameter electrode.
Electrode sticks to work-
piece.
Arc length too short. 1.
Output Amp setting too low. 2.
Lift electrode to correct arc length as soon 1.
as arc is struck.
Increase output Amp setting or change to
2.
smaller diameter electrode.
Electrodes sputter and
stick.
Damp electrodes. 1. Use dry electrodes and store in a dry 1.
location.
Weld bead does not pen-
etrate base metal.
Travel speed too fast. 1.
Arc length too short. 2.
Output Amp setting too high. 3.
Decrease travel speed. 1.
Increase arc length. 2.
Reduce output Amp setting. 3.
Ragged depressions at
edge of weld.
Slow and/or inconsistent travel speed. 1.
Output Amp setting too high. 2.
Increase and maintain travel speed. 1.
Reduce output Amp setting. 2.
