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.

Step 3. RECOMMENDED

COURSE OF ACTION

The last column labeled “Recommended Course of Action” lists the most likely com- ponents that may have failed in your machine. It also specifies the appropriate test procedure to verify that the subject com- ponent is either good or bad. If there are a number of possible components, check the components in the order listed to eliminate one possibility at a time until you locate the cause of your problem.

All of the referenced test procedures referred to in the Troubleshooting Guide are described in detail at the end of this chapter. Refer to the Troubleshooting and Repair Table of Contents to locate each specific Test Procedure. All of the specified test points, components, terminal strips, etc. can be found on the referenced electrical wiring diagrams and schematics. Refer to the Electrical Diagrams Section Table of Contents to locate the appropriate diagram.
