CWF-50 Cold Wire Feeder
- 7 -
Section III
Installation
As standard, the unit is provided with 6 ft. (1830
mm) of cable between the control and the wire
drive assembly. The control is typically mounted
near the feeder due to the length of the control
cable.
1.
To mount the wire drive assembly, trans-
fer mounting holes from the wire feeder’s
aluminum mounting plate to the mount-
ing surface. (See Figure 2 for mounting
hole dimensions.)
2. The 9629 control must be mounted in
a suitable manner providing adequate
ventilation. The control should not be
mounted in a high temperature environ-
ment.
3. Slip the wire guide positioner onto the
torch barrel and tighten the wing nuts.
You may choose from one of three sets
of mounting holes depending upon the
brand of the torch to be used.
The wire guide tip angle should be set
roughly by positioning the guide and
tightening the screw. The tip should be
approximately on the same level as the
tungsten.
4. Select the wire feed accessory kit for the
size wire your application requires. The
kit will include inlet and outlet guides,
conduit, wire guide tip, and feed rolls. Be
sure all components match the wire size
to be used. (Refer to Figure 3)
Proper installation of the wire feed kit is
very critical to the successful operation
of the cold wire feed unit. Proper instal-
lation helps avoid “bird-nesting” at the
feed rolls and smooth wire feed delivery
into the weld puddle.
a. The inlet guide should be inserted
until the “set screw” properly aligns
with the notched section on the
guide. The closer the tapered tip is
to the feed rolls the better.
b. The intermediate guide needs to be
inserted prior to the mounting of the
feed rollers. The intermediate guide
also has a “notched” section which
should align with the screw holding
it in position.
c. The feed rolls need to be mounted
securely. If not tightened, they will
loosen and will eventually fall off.
d. The conduit assembly is then fitted
into the outlet guide assembly. This
step may need to be repeated in or-
der to fit it correctly. First, the end
and inside of the conduit must be
deburred. The wire must slide freely
into the conduit.
Next the conduit should be cham-
fered. The conduit needs to be as
close as possible to the feed rolls
in order to avoid “bird-nesting”,
especially on soft wires. Putting a
chamfer on the conduit allows you
to get the conduit very close to the
feed rolls.
At this point, slide the conduit
through the outlet guide. You
should extend the conduit beyond
the tapered end of the outlet guide
approximately 1/4” (6 mm). Tighten
the set screw securely, holding the
conduit properly in position.
