B. INSTALL LINER
For Soft Wire:
1.
Lay gun cable out relatively straight.
2.
Remove liner positioner nut.
3.
Insert end of plastic liner into opening at inlet con-
nection end of cable, and then inch liner through
cable until it butts to a stop. Inch the liner back and
forth to be sure it is seated. Then pull liner back
about 1/4”. When assembling the 1/16-in. liner,
whipping the cable/hose bundle from side to side
will facilitate the assembly. It is also advisable to
remove any sharp edges (tapered end) from the
liner end.
4.
Slide collet on liner and up and into inlet connector
end of cable, and then slide O-ring up to collet.
Finally, slide liner positioner nut onto the liner and
engage it to the connector. The small teeth inside
the slotted collet will keep the liner tight in the gun
and cable when the liner positioner nut is hand tight-
ened.
5.
The liner should be extending several inches past
the positioner nut. Insert the liner through the wire
feeder connector assembly, including the support
tube for 0.030/0.035 liners. (The support tube
should be removed for 1/16-in. wire.)
6.
Connect the wire feeder connector assembly to the
gun cable hand tight.
7.
Trim the liner. When wire feeder connector assem-
bly is assembled to the accessory support of the
wire feeder, the liner should be trimmed as close
as possible but not touching the feed roll as illus-
trated below.
For Hard Wire:
1.
Remove the liner positioner nut from the inlet con-
nector.
2.
Lay the gun cable out relatively straight.
3.
Insert the bare end of the steel liner into the con-
nector and inch through the torch until it butts to a
stop.
4.
Measure the distance from the end of the inlet con-
nector to the liner ferrule shoulder as shown be-
low.
5.
Remove the liner and cut this amount off the bare
end of the liner. Remove burrs both inside and
outside cut end.
6.
Reassemble liner.
7.
Reassemble positioner nut and tighten.
C. MOUNT POWER CONTROL ASSEMBLY
1.
The Power Control Assembly (19310) is supplied
with two tube clamps and screws for mounting on
the frame of the MIG-35 Wire Feeder as shown in
Fig. 2. Threaded holes are provided in the box for
the screws.
2.
Insert the cord with 3 leads through strain relief of
the wire feeder control assembly along with its con-
trol cord. Connect the black and white leads to the
same terminals as the gas solenoid valve. TB2-3
& TB2-4 on MIG-35; T1-2 & T1-3 on Digimigs —
refer to appropriate wire feeder instruction booklet
or see Fig. 2A.) Connect green to appropriate chas-
sis ground. The connections will supply 110 V AC
to the power control assembly.
3.
Connect the cord with socketed connector to the
mating connector of gun. This connection will sup-
ply 42 V to the drive motor of the gun.
D. CONNECT MIG-35 WIRE FEEDER CONNEC-
TOR ASSEMBLY LEADS
1.
The Wire Feeder Connector Assembly is equipped
with power cable, gas hose, and switch cord. Con-
nect them to wire feeder as shown in Fig. 2.
