1. Check circuit fuse or circuit breaker
2. Power cable requires service
1. Check work clamp, cable and connection to work piece.
Check electrode cable and clamp
2. Check all welder external connections
1. Avoid contact with work piece
2. Make sure clothing and work area are dry
1. If possible, relocate welder to avoid use of extension cord. If
relocation of welder is not possible, use thicker (lower gauge
number) extension cord
2. Use smaller diameter electrode
3. Welder requires a
dedicated
115V circuit
1. Verify that electrode is for alternating current (AC) use
2. Use smaller diameter electrode
3. Verify proper grounding. (No paint, varnish or corrosion)
4. Run welder on dedicated 115V circuit
Welder does not hum when
turned on
Welder hums but does not
weld
Welder gives trickle shocks
Welder overheats - blows
fuses, trips circuit breaker
Arc difficult to strike
