F-25

SWITCH BOARD TEST

WARNING

Service and repair should be performed by only Lincoln Electric factory trained personnel. Unauthorized repairs performed on this equipment may result in danger to the technician or machine operator and will invalidate your factory warranty. For your safety and to avoid electrical shock, please observe all safety notes and pre- cautions detailed throughout this manual.

If for any reason you do not understand the test procedures or are unable to per- form the test / repairs safely, contact the Lincoln Electric Service Department for electrical troubleshooting assistance before you proceed. Call 1-888-935-3877.

TEST DESCRIPTION

This procedure will determine if the Switch Boards are working properly. This resis- tance test is preferable to a voltage test with the machine energized because these boards are easily damaged. Also, it is more dangerous to work on these boards when power is applied.

MATERIALS NEEDED

ANALOG Volt/Ohm Meter (multi-meter)

Misc. Hand Tools

Wiring Diagram (Section G)

NOTE: Most digital meters will not supply enough current in the “ohms” mode to do this test effectively.
