code
Meaning
Solution
Err Uol
(Error Voltage)
Input voltage and Voltage Switch
setting do not match.
Flip Voltage Switch.
Our Cur
(Over current)
Welder is using too much current.
Welder may pull too much current from supply.
Reduce current/wire speed
using Wire Speed Knob.
Err Sht
(Error Short)
Electrode has shorted against workpiece,
no arc is detected. The electrode is stuck
against the workpiece, allowing all current
to go directly through without welding.
Free the electrode from the plate.
Alarm indicator
without code.
Fan keeps running.
Welder has overheated.
Duty Cycle was likely exceeded.
Follow instructions under Duty Cycle
(Duration of Use) on page 18.
troubleshooting
iMportant!
Be cErtain to shut off the Welder, disconnect it from power, and discharge the Mig gun to
ground before adjusting, cleaning, or repairing the unit.
problem
possible causes
likely Solutions
Wire feed motor
runs but wire does
not feed properly
1. Insufficient wire feed tension.
2. Incorrect wire feed roller size.
3. Damaged MIG Gun, cable, or liner assembly.
4. Feed Tensioner is too tight.
1. Increase wire feed tension properly.
Follow step 31 on page 16.
2. Flip roller to correct size, follow the
Feed Roller instructions on page 13.
3. Have a qualified technician inspect these
parts and replace as necessary.
4. Loosen Feed Tensioner so it applies only
enough pressure to prevent continued
spinning after the Gun Trigger is released.
Wire creates a bird’s
nest during operation
1. Excess wire feed tension.
2. Incorrect Contact Tip size.
3. MIG Gun Cable Connector not fully
inserted into Wire Feed mechanism.
4. Damaged liner.
1. Adjust wire feed pressure properly.
Follow step 31 on page 16.
2. Replace with the proper tip for wire used.
3. Insert Gun Cable Connector properly.
Follow steps 15 and 16 on page 14.
4. Have a qualified technician inspect
and repair/replace as necessary.
Wire stops
during welding
1. Gun cable is severely bent and Wire
Feed mechanism cannot feed wire.
2. Gun liner is clogged or worn.
3. Gun liner is too small for
welding wire being used.
4. Wire is tangled on the spool.
5. Wire is not making contact with Feed Rollers.
6. Feed Roller is not making enough contact
with wire or is crushing flux-cored wire.
1. Straighten Gun cable.
2. Check gun liner for obstruction. Replace if necessary.
3. Check that gun liner is correct size for wire.
4. Check wire for cross winding or
tangled spool.
5. Check Feed Rollers and ensure correct
groove for wire diameter is being used.
6. Check Feed Tensioner and ensure it is set properly.
Follow all safety precautions whenever diagnosing or servicing the equipment.
