Operating Instructions and Parts Manual
Maintenance
Disconnect power
supply and turn
machine off before inspecting or
servicing any components.
BefORe eVeRy USe:
1.
Check condition of weld cables and
immediately repair or replace any
cables with damaged insulation.
2.
Check condition of power cord and
immediately repair or replace any
cord if damaged.
Troubleshooting Chart
Symptom
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
Bead is intermittently too
thin
Bead is intermittently too
thick
Ragged depressions at edge
of weld
Weld bead does not
penetrate base metal
Electrode sticks to work
piece
Electrodes sputter and stick

3.
Check condition of electrode holder
insulating pieces and immediately
replace cracked or missing
insulators. Verify that all fasteners
are tight and insulated.
with cracked or missing insulation on
welding cables, electrode holder, or
power cord.
Possible Cause(s)
1. No power at receptacle
2. Broken or damaged power cable
1. Inadequate current at electrode
2. Poor connections at welder
1. Accidental contact with work piece
2. Current leakage caused by moist
clothing or work area
1. Use of extension cord
2. Electrode diameter too large
3. Overloaded circuit
1. Electrode diameter too large
2. Work piece not properly grounded
3. Heavy loads making power line
voltage low
1. Inconsistent travel speed
2. Output amp setting too low
1. Slow and/or inconsistent travel speed
2. Output amp setting too high
1. Travel speed too fast
2. Arc length too short
3. Output amp setting too high
1. Inconsistent travel speed
2. Output amp setting too low
Electrode is held in contact with work
piece while arc is struck

eVeRy 3 MOnThS:
Replace any unreadable labels on the
welder. Use compressed air to blow
all dust and lint from the ventilation
openings.
Do not operate this
welding machine
Corrective Action
1. Check circuit fuse or circuit breaker
2. Power cable requires service
1. Check ground 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, relocated 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 230v circuit
1. Use smaller diameter electrode
2. Verify proper grounding. (No paint, varnish or corrosion)
3. Run welder on dedicated 230v circuit
1. Decrease and maintain travel speed
2. Increase output amp setting or change to smaller diameter
electrode
1. Increase and maintain travel speed
2. Reduce output amp setting
1. Decrease travel speed
2. Increase arc length
3. Reduce output amp setting
1. Decrease and maintain constant travel speed
2. Increase output amp setting
Lift electrode to correct arc length as soon as arc is struck
Use dry electrodes and store in dry location
