4.Check for proper trigger switch operation. Remove the torch cable assembly from the Pro Cut and test for continuity between 9 and 1 at the quick connect when the trig- ger switch is depressed and no continuity when the switch is not depressed. Replace the trigger switch or torch cable if defective.

5.Possible faulty Control board.

6.Possible faulty Output Power board.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
