LEFT SIDE OF MACHINE

PROCEDURE

1.Remove input power to the TIG 225 machine.

2.Using the 3/8” nutdriver remove the right side panel.

3.Locate the Spark Gap Assembly at the right side of the machine. See Figure F.1.

4.With the 5/64” Allen type wrench loosen the set screw holding the upper electrode in place.

5.Increase the distance between the electrodes to at least 3/8” by sliding one electrode away from the other electrode. Secure the one elec- trode in this position.

6.This should disable the high frequency circuit.

Visually check to make sure high frequency sparking is NOT present before connecting any test equipment to the TIG 225 machine.

7.When voltage testing and scope measurements are complete reset the spark gap electrodes to

.020” air gap. Tighten the set screw using the 5/64” Allen wrench.
