Check cable connections between the power
source and the user interface.

of the machine.

Check the setup for proper air flow around and
through the system.

Check that the system has been properly
maintained, including removal of accumulated
dust and dirt from the intake and outlet louvers.

When the machine has cooled down to a safe
level, the interface signals this by flashing two
LEDs next to Button or start welding operation
by the torch trigger.

Remove tight bends from the gun and cable.

Check that the spindle brake is not too tight.

Verify the adequacy of the electrode to the
welding process.

Verify a high quality electrode is being used.

Check drive rolls alignment and gears.

Wait for the error to reset and the motor to cool
(approximately 1 minute).

Make sure there is enough coolant in the tank
and that auxiliary power is supplied.

Make sure the pump is working. When the
trigger is pulled the pump should run.
