(1)FLASHING THE FIELDS

AC Auxiliary Power:

1.Stop the engine welder and remove the cover from the exciter.

2.Turn the “Fine Adjustment Control” (rheostat) to “100” on the dial.

3.Using a 12 volt automotive battery, connect its negative terminal to the negative brushholder. The negative brushholder is the one nearest to the rotor lamination. See the wiring diagram. With the engine NOT running, touch the positive battery terminal to the positive brushholder. Remove the battery from the circuit.

4.Replace the exciter cover. Start the welder and the generator voltage should build up.
