FIGURE F.3 – DRIVE MOTOR TEST
PROCEDURE
1. Remove input power to wire feed
unit.
2. Using the 3/8 in. nut driver, remove
the cover from the wire feeder.
3. Locate the two quick connectors in
the two motor armature leads. Refer
to Figure F.3. Do NOT disconnect
the leads.
4.
Apply the correct input power (from
the Power Wave 455 control cable) to
the wire feede. Activate the gun
trigger and with the motor running
check at the quick connectors [#550
White (+) to #551 / Black (-)] for
approximately 1 VDC to 32 VDC
dependent upon motor speed. The
motor speed should vary with
changes in motor armature voltage.
5. If the correct voltages are NOT
present at the motor leads, check the
associated leads between the motor
and plug J83 on the feedhead board.
If the leads are OK, the feedhead
board may be faulty.
6. If the correct voltages are present at
motor armature leads and the motor
does not run and vary speed with
changes in armature voltage, the
motor or gear box may be faulty.

Removal and Replacement.
7. Install the wire feeder cover using the
3/8 in. nut driver
