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, transfer mounting holes from the wire fe eder’s
aluminum mounting plate to the mounting surface. (See Figure 2 for mounting hole
dimensions.)
2. The 9700W control must be mounted in a suitable manner providing adequate
ventilation. The control should not be mounted in a high temperature environment.
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 installation 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 order 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 chamfered. 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.
