Welder; Welds - Campbell Hausfeld GR2100 Manual De Instrucciones Y Lista De Piezas

Troubleshooting Chart (Continued)

Welder

Symptom Possible Cause(s)
Welder runs but 1. Inadequate current at electrode
does not weld
2. Poor connections at welder
3. Open, shorted, or incorrect wiring
4. Faulty capacitor
5. Open or shorted field windings
6. Open diodes
Welder gives 1. Accidental contact with work piece
trickle shocks 2. Current leakage caused by moist clothing
or work area
Arc diffi cult to 1. Wrong type of electrode.
strike 2. Electrode diameter too large
3. Work piece not properly grounded
4. Engine speed is too slow
★ These diagnostic and repair procedures should be performed by an authorized service center.

Welds

Symptom Possible Cause(s)
Bead is 1. Inconsistent travel speed
intermittently 2. Output amp setting incorrect
too thin or too
thick
Ragged 1. Travel speed too fast
depressions at 2. Arc length too short
edge of weld 3. Output amp setting too high
Weld bead does 1. Inconsistent travel speed
not penetrate base 2. Output amp setting too low
metal 3. Electrode diameter too large
Electrode sticks 1. Arc length short
to workpiece 2. Amp setting low
3. Incorrect electrode
Electrodes Damp electrodes

Corrective Action
1. Check work clamp, cable and connection to work piece. Check electrode
cable and clamp
2. Check all welder external connections
3. Referring to the wiring diagram, clean and reconnect all wiring ★
4. Replace capacitor ★
5. Test winding resistance, replace field winding if necessary ★
6. Test diodes, replace if necessary ★
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
