TEST PROCEDURE

1.Remove main supply power to the machine.

2.Using the 3/8” nut driver, remove the case left and right side covers.

3.Locate plug J8 on the control board. See Figure F.2.

WARNING

ELECTRIC SHOCK can kill.

With input power ON, there are high voltages inside the machine. Do not reach into the machine or touch any internal part.

4.Carefully apply the correct input power mak- ing certain the reconnect configuration at the reconnect panel is correct for the input volt- age applied. Turn the TIG 275 ON.

5.Using the voltmeter, carefully test for the cor- rect transformer secondary voltages per Table F.1.
