POWER MIG 255C

4. Locate plug J6 on the control PC board.

See Figure F.1.

NOTE:

The location of plugs may vary

depending on the machine code.

5. Locate the following leads on plug J6

on the control PC board:

TEST PROCEDURE

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

----------------------------------------------------------

NOTE:

Secondary voltages will vary pro-

portionately with the primary input voltage.

1. Disconnect the main input power sup-

ply to the machine.

2. Remove the case top and side panels

with a 3/8 in. nutdriver.

3. Remove the tool tray with a 5/16 in. nut-

driver.
