COURSE OF ACTION

The welding arc is “cold.” The welding arc is not stable or is not satisfactory. the engine runs nor- mally. The auxiliary power is nor- mal.

1.Make sure the MODE selector switch is in the correct position for the process being used. (For example, CV-WIRE, PIPE, CC- STICK.)

2.Make sure the electrode (wire, gas, voltage, current etc.) is cor- rect for the process being used.

3.Check for loose or faulty con- nections at the weld output ter- minals and welding cable con- nections.

4.The welding cables may be too long or coiled, causing an exces- sive voltage drop.

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

Contact your local Lincoln

Authorized Field Service Facility.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
