Troubleshooting Chart - Generator (Continued)
Symptom possible Cause(s)
Auto-Idle does 1 . Damaged or disconnect wire in idle
not work control circuit .
2 . Failed idle control circuit board .
3 . Failed current sensing coil .
H These diagnostic and repair procedures should be performed by an authorized service center .
Troubleshooting Chart - Welder
Symptom possible Cause(s)
Welder runs but 1 . Inadequate current at electrode
does not weld
2 . Poor connections at welder
3 . Front panel switch set incorrectly
4 . Open, shorted, or incorrect wiring
5 . Faulty capacitor
6 . Open or shorted field windings
7 . Open diodes
Welder gives trickle 1 . Accidental contact with work piece
shocks 2 . Current leakage caused by moist
clothing or work area
Arc difficult to strike 1 . Wrong type of electrode .
2 . Electrode diameter too large
3 . Work piece not properly grounded
4 . Engine speed is too slow
H These diagnostic and repair procedures should be performed by an authorized service center .

Corrective Action
1 . Repair or replace wiring .
2 . Replace idle control board .
3 . Replace current sensing coil .
Corrective Action
1 . Check work clamp, cable and connection to work piece . Check
electrode cable and clamp
2 . Check all welder external connections
3 . Set front panel switch to weld
4 . Referring to the wiring diagram, clean and reconnect all wiring H
5 . Replace capacitor H
6 . Test winding resistance, replace field winding if necessary H
7 . Test diodes, replace if necessary H
1 . Avoid contact with work piece
2 . Make sure clothing and work area are dry
1 . Verify that electrode is for alternating current (AC)
2 . Use smaller diameter electrode
3 . Verify proper grounding . (No paint, varnish or corrosion)
4 . Adjust engine speed
Corrective Action
1 . Carefully watch and control the width of the molten weld bead
2 . Adjust output amp setting or change to smaller diameter electrode
1 . Watch orange molten weld puddle and control bead width
2 . Practice running electrode across workpiece with welder OFF
3 . Reduce output amp setting
1 . Decrease and maintain constant travel speed
2 . Increase output amp setting
3 . Change to smaller diameter electrode
1 . Lift electrode to correct arc length as soon as arc is struck
2 . Increase amp setting or change to smaller diameter electrode
3 . Verify electrode is suitable for 62 .5 V open circuit voltage
Use dry electrodes and store in dry location
