A-5 INSTALLATION
POWER FEED 11
A-5
RATIO CHANGE PROCEDURE:
1) Power down the Power Feed by turning OFF its
companion PowerWave power source. For maxi-
mum safety, disconnect the control cable from the
Power Feed.
2) Pull open the Wire Feeder’s Compartment Door.
3) Remove the Feedplate per the following:
a) Disconnected the Electrode from the Feedplate
b) Pull open the Wire Drive Pressure Door.
c) Using a 3/16" Hex Key Wrench remove the two
screws that secure the Feedplate to the
Interface Plate. These screws are located just
below and to the right and just below and to left
of the lower drive gears.
d) Swing the rear of the Feedplate out towards
the front of the machine which will allow it to be
pulled back and out of the machine.
Note: The shielding gas hose and gun leads are still
attached to the Feedplate. This is OK provided that
the Feedplate is setting on a suitable surface such
that no excess tension is being place on the gas hose
and gun leads. If necessary remove the gas hose and
disconnect the leads.
4) Remove the pinion gear as follows:
a) Using a phillips head screwdriver remove the
screw that secures the gear to the output shaft
of the gearbox and remove the gear.
b) Lightly cover the output shaft with engine oil or
equivalent. Install appropriate size gear(small
gear for low speed and a large gear for high
speed) onto output shaft and secure with flat
washer, lock washer, and Phillips head screw
which were previously removed.
Note: Be sure that the woodruff key remains secured
to the output shaft during the gear change.
5) Position the Motor/Gearbox as follows:
a) There are 4 screws that secure the
Motor/Gearbox to the Interface Plate. Using a
3/16" Hex Key Wrench remove the 2 upper
screws and loosen (but don’t remove) the 2
lower screws.
b) Slide the Motor/Gearbox to the
UPPER SET OF HOLES FOR LOW SPEED
LOWER SET OF HOLES FOR HIGH SPEED.
c) Secure in position with flat washers, lock wash-
ers, and socket head screws that were previ-
ously removed and loosened.
6) Re-attach Feedplate (and gas hose and gun leads
if they were removed) that was removed in Step 3
and reconnect the Electrode Cable.
Note: The screws that secure the Feedplate to the
Interface Plate must go thru the insulator bushings in
the Feedplate.
7) Close the Wire Drive Pressure Door and Wire
Feeder’s Compartment Door.
8) Set the High/Low Dip Switch on Feed Head PC
board as follows:
a) Remove the left case side as follows:
- Remove 4 screws that directly secure the
case side
- Loosen the 3 screws that secure the lower
skid rail. This will free the case side edge
and allow it to be lifted up and removed.
Note: PF-11's that have been installed horizontally on
top of the Power Source will need to remove the
Mounting Bracket in order to access the the left case
side.
b) Locate the 8-position DIP switch (S1) on the
Feed Head PC board. The setting will be made
on the bottom most switch, DIP switch #8.
c) Using a pencil or other small object, to slide the
switch left, to the “OFF" position, when the low
speed gear is installed. Conversely, slide the
switch right, to the “ON" position, when the high
speed gear is installed. Refer to the diagrams
below.
Setting for Low Speed Setting for High Speed
d) Replace the left case side and screws(and
Mounting Bracket if required). The PC board
will “read” the switch at power up, automatically
adjusting all control parameters for the speed
range selected.
