PROBLEMS

(SYMPTOMS)

Thermal light is ON. The machine regularly “overheats.”

POSSIBLE AREAS OF

MISADJUSTMENT(S)

OUTPUT PROBLEMS

1.The welding application may be exceeding the recommended duty cycle and/or limits of the machine.

2.Dirt and dust may have clogged the cooling channels inside the machine. Refer to the Maintenance Section of this manual.

3.Air intake and exhaust louvers may be blocked due to inadequate clearance around the machine. Check the upper section of the machine and AC/DC switch lower section intakes.

4.Make sure the fan is functioning correctly. Machines are equipped with F.A.N. (fan as needed) circuitry. The fans run whenever the output is enabled and will continue running for a period of time (approximately 5 minutes) after the output is disabled.

RECOMMENDED

COURSE OF ACTION

1.One of the thermostats may be faulty. Also check associated wiring for loose or faulty connections. See the Wiring Diagram or the Machine Diagram in Section G. There are a total of 2 thermostats in the system.

2.Temporarily jumper out the thermostat circuit at the Control Board. See the Machine Diagram in this manual to jump this circuit function for test only. If the machine does not reset, the Control Board is defective. If it does reset, perform the Thermostat Test.

3.Temporarily jump around the fan relay contacts to test fan relay function. See the Machine Diagram in Section G to test the fan relay function.

CAUTION: 120VAC is used to run the fan.
