TROUBLESHOOTING AND REPAIR

F-55

ROCKER ADJUSTMENT PROCEDURE

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 precautions detailed throughout this manual.

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

TEST DESCRIPTION

The rocker is the part of the welding generator that supports and positions the 4 sets of brushes. Its position can be adjusted to fine tune the weld output and influence the weld characteristics.

IMPORTANT: The rocker is set at the factory for the best overall performance and long generator and brush life. Altering this adjustment is normally not recom- mended unless one or more of the welding generator components affect- ing this setting have been replaced. In very unusual situations, very small adjustments of the rocker may be beneficial if the machine is oper- ating within the specified limits, but the arc characteristics are unsatisfac- tory for the desired application.

CAUTION: Improper rocker adjustment can result in poor performance, reduced brush life and damage to the welding generator. This adjustment should only be attempted by an experienced professional.

MATERIALS NEEDED

Resistive load bank, capable of absorbing at least a 500 Amp load.

Volt meter

Ammeter, able to read at least 500 Amps

Miscellaneous hand tools

Drill with 1/8” bit

Tachometer or frequency meter.
