6.1 Safety Precautions
Service and Repair should only be performed by Nelson Stud Welding, Inc. Factory Trained
Personnel . Unauthorized repairs performed on this equipment may result in danger to the technician
and machine operator and will invalidate your factory warranty. For your safety and to avoid
Electrical Shock, please observe all safety notes and precautions detailed throughout this manual.
This Troubleshooting Guide is provided to help you locate and remedy possible problems with
machine setup or operation. Simply follow the three-step procedure listed below.
Step 1. LOCATE PROBLEM (SYMPTOM). Look under the column labeled “Problem”. This
column describes possible symptoms that the machine may exhibit. Find the listing that best
describes the symptom that the machine is exhibiting.
Step 2. PERFORM EXTERNAL / INTERNAL TESTS. The second column labeled “Possible
Cause” lists the obvious external possibilities that may contribute to the machine symptom. Perform
these tests/checks in the order listed. Many “Solutions” can be verified without removing the case
cover. However, more thorough investigation may require examination of the inner machine contents.
Use extreme caution when repairing any component within the case, and follow all safety guidelines
set forth in this manual.
Step 3. SEEK PROFESSIONAL ASSISTANCE. If you have exhausted all of the recommended tests
in Step 2, consult your Local Authorized Nelson Field Service Facility.
If for any reason you do not understand the test procedures or are unable to
perform the tests/repairs safely, contact your LOCAL AUTHORIZED NELSON
FIELD SERVICE FACILITY for assistance before you proceed.
