1.Remove input power to the TIG 275 machine.

2.Using the 3/8” nut driver, remove the case sides.

3.With the needle nose pliers, remove the two secondary leads from the quick-connects on the high frequency arc starter board assem- bly. See Figure F.9.

4.Disconnect the in-line splice quick connect from one primary lead to lead #238. Cut any necessary cable ties.

5.Remove the lead splice from the other prima- ry lead that is connected to lead #237, C6 capacitor and R5 resistor. See the Wiring Diagram. Cut any necessary cable ties.

6.Using the phillips head screw driver, remove the front mounting screw from the base of the high voltage transformer. Take note of insula- tor placement for reassembly.

7.With the phillips head screw driver, loosen the two rear mounting screws.

8.Carefully slide the transformer forward and remove it from the TIG 275 machine.
