This Troubleshooting Guide is provided to help you locate and repair possible machine malfunctions. Simply follow the three-step
procedure listed below.
Step 1. LOCATE PROBLEM (SYMPTOM). Look under the column labeled “PROBLEM (SYMPTOMS)”. This column describes pos- sible symptoms that the machine may exhib- it. Find the listing that best describes the symptom that the machine is exhibiting. Symptoms are grouped into the following categories: output problems, function prob- lems, wire feeding problems, and welding
problems.
Step 2. PERFORM EXTERNAL TESTS. The second column labeled “POSSIBLE AREAS OF MISADJUSTMENT(S)” lists the obvious external possibilities that may con- tribute to the machine symptom. Perform these tests/checks in the order listed. In general, these tests can be conducted with- out removing the case wrap-around cover.
