OUTPUT PROBLEMS

The machine will not produce more than 200 amps.

1.This may be normal operation. If the output current exceeds 290 amps, an electronic protection circuit will reduce the current to less than 200 amps. The machine will continue to produce this low current until the protection circuit is reset. Reset occurs when the output load is removed.

2.Check the input voltage and input voltage reconnect procedures. See Input Voltage Reconnect Procedure.

3.Check for loose or faulty welding cables.

If all recommended possible areas of misadjustment have been checked and the problem persists, Contact your local Lincoln Authorized Field Service Facility.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, con- tact your local authorized field service facility for technical troubleshooting assistance before you proceed.
