FEEDING PROBLEMS

RECOMMENDED COURSE OF ACTION

Rough wire feeding or wire will not feed but drive rolls are turning.

1.The gun cable may be kinked or twisted.

2.The wire may be jammed in the gun cable, or gun cable may be dirty.

3.Check drive roll tension and position of grooves.

4.Check for worn or loose drive rolls.

5.The electrode may be rusty or dirty.

6.Check for damaged or incorrect contact tip.

7.Check wire spindle for ease of rotation and adjust break ten- sion knob if necessary.

8.Check that the gun is pushed all the way into gun mount and properly seated.

If all recommended possible areas of misadjustment have been checked and the problem persists,

Contact your local Lincoln Authorized Field Service Facility.
