PROCEDURE

WARNING

THE ON/OFF POWER SWITCH will be “hot” during these tests.

NOTE: Secondary voltages will vary proportionately with the primary input voltage.

1.Disconnect the main input power supply to the machine.

2.Remove the case top and side panels with a 3/8” nutdriver.

3.Remove the tool tray with a 5/16” nut driver.

4.Locate leads X2 thru X8 located on the output selector switch. See Figure F.1.

5.Locate lead X1 located on the output rectifier assembly. See Figure F.2.

6.Locate leads X9 and X10. See Figure F.3.

7.Connect main input power to the machine.

8.Turn the Power MIG® 215XT ON/OFF Power Switch to the ON position.

WARNING

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts such as output terminals or inter- nal wiring.

•All input power must be electrical- ly disconnected before proceed- ing.

9.Carefully make the following voltage tests. See Table F.1.

10.Turn Off the machine.

11.If any of the voltages are incorrect or missing, check for loose or broken connections between the main transformer and the test points.
