IMPORTANT!

Be CERTAIN to shut off the Welder, disconnect it from power, and discharge the Torch to ground before adjusting, cleaning, or repairing the unit.

Wire feed motor runs but wire does not feed properly

POSSIBLE CAUSES AND SOLUTIONS

1.Insufficient wire feed pressure:

Increase wire feed pressure properly - follow step 17 on page 17.

2.Incorrect wire feed roll size:

Flip roll to correct size, follow the Wire Spool Installation instructions, starting on page 12.

3.Damaged Torch, cable, or liner assembly:

Have a qualified technician inspect these parts and replace as necessary.

Wire creates a bird’s nest during operation

POSSIBLE CAUSES AND SOLUTIONS

1.Excess wire feed pressure:

Adjust wire feed pressure properly - follow step 17 on page 17.

2.Incorrect contact tip size:

Replace with the proper tip for wire used.

3.Torch end not inserted into drive housing properly:

Loosen torch securing bolt and push torch end into housing just enough so that it does not touch wire feed mechanism.

4.Damaged liner:

Have a qualified technician inspect and repair/replace as necessary.

Welding arc not stable

POSSIBLE CAUSES AND SOLUTIONS

1.Wire not feeding properly:

See first Troubleshooting section above.

2.Incorrect contact tip size:

Replace with the proper tip for wire used.

3.Incorrect wire feed speed:

Adjust wire feed speed to achieve a more stable arc.

4.Loose Torch cable or ground cable: Check to ensure that all connections are tight.

5.Damaged Torch or loose connection within Torch:

Have a qualified technician inspect and repair/replace as necessary.

Weak Arc strength

POSSIBLE CAUSES AND SOLUTIONS

1.Incorrect line voltage:

Check the line voltage and, if insufficient, have a licensed electrician remedy the situation.

2.Improper gauge or length of cord:

Extension cords are not recommended. If possible, eliminate the use of an extension cord.

If a longer cord is needed, refer to the replacement cord guidelines on page 7.

3.Not enough current:

Switch current to proper setting for metal thickness.
