CHANGING THE WIRE DRIVE RATIO
ELECTRIC SHOCK can kill.
• Turn off power to the power source
at the disconnect switch.
------------------------------------------------------------------------
Changing the ratio requires a gear change and a PC
board switch change. The Power Feed Wire Feeders
are shipped with both high speed and a low speed
gears. As shipped from the factory, the low speed
(high torque) gear is installed on the feeder. For iden-
tification purposes, the low speed (high torque) gear
has 20 teeth and is 1.1 inches in diameter. The high
speed gear has 30 teeth and is 1.6 inches in diameter.
1. Pull open the Pressure Door.
2. Remove the Phillips head screw retaining the pinion
gear to be changed and remove the gear. If the
gear is not easily accessible or difficult to remove,
remove or adjust feed plate from the gearbox. To
remove feed plate:
• Loosen the clamping collar screw using a 3/16"
Allen wrench. The clamping collar screw is
accessed from the bottom of the feed plate. It is
the screw which is perpendicular to the feeding
direction.
• Loosen the retaining screw, which is also
accessed from bottom of feeder, using a 3/16"
Allen wrench. Continue to loosen the screw until
the feed plate can be easily pulled off of the wire
feeder.
3. Loosen, but do not remove, the screw on the lower
right face of the feed plate with a 3/16" Allen
wrench.
4. Remove the screw on the left face of the feed plate.
If changing from high speed (larger gear) to low
speed (smaller gear), line the lower hole on the left
face of the feed plate with the threads on the
clamping collar. Line the upper hole with the
threads to install larger gear for high speed feeder.
If feed plate does not rotate to allow holes to line
up, further loosen the screw on right face of feed
plate.
5. Remove the small gear from the output shaft.
Lightly cover the output shaft with engine oil or
equivalent. Install gear onto output shaft and secure
with flat washer, lock washer, and Phillips head
screw which were previously removed.
6. Tighten the screw on lower right face of feed plate.
7. Re-attach feed plate to wire feeder if removed in
Step 2.
8. Feed plate will be rotated out-of-position due to the
gear change. Adjust the angle of the feed plate per
Item 2.
Set the High/Low switch code on Wire Drive PC board
which is located on the Power Wave 455/R and
Power Wave 655/R. Consult the Instruction Manual
for proper power source settings.
