3.
Turn OFF welder POWER SWITCH.
Open the welder side panel.
Loosen the tension arm and lift it
up off the drive roller.
4. Turn the wire spool counter-
clockwise (be sure to hold onto the
wire itself while turning the spool or
the wire will unspool itself when it
becomes free of the gun liner),
removing wire from gun assembly.
5. Remove two 1_ inch hex head
screws (may also be removed with
a straight blade screwdriver) and
one pan head Phillips screw (inlet
guide tube end) from the drive
roller and lift away the strain relief
clamp that holds the tail end of the
gun in the drive assembly.
6. Leave the gun assembly (consists
of nozzle, gas diffuser, conductor
tube, handle and cable containing
gas tubing electrical cable and
liner) attached to the welder but
move the welder to a place where
the gun assembly can be laid out
straight on a table or workbench or
similar flat surface.

9,
Unscrew and remove the nozzle.
With a crescent wrench (six or eight
inch), turn the gas diffuser
clockwise (has left hand threads)
and remove the gas diffuser (and
contact tip together) from the
conductor tube on the end of the
gun.
Remove the four Phillips head
screws that hold the handle case
together. With the exception of the
trigger, completely remove the
contents of the handle case.
10. Cut the plastic cable tie away from
the cable covering (tubing).
Note: In the following procedure step,
it may be necessary to remove
the gas fitting from the gas
valve in order to make room to
turn out the head end of the
gun liner.
11. With a 5/16 inch open end wrench,
unscrew the head end of the liner
from the gas valve. Save the
internal star lock-washer and note
the orientation of the live wire
terminal. If you find it necessary to
remove the gas hose connector,
press down on the ring at the rear
of the gas fitting to release the gas
hose and pull out the gas hose.
Remove the gas fitting with a 9 mm
open end wrench or three inch
crescent.
12. Pull the liner out of the cable
covering (tubing) from the handle
end and push the small piece of
liner out of the conductor tube.
13. Carefully insert the new liner into
the cable taking particular care to
keep the liner straight (especially at
the terminal end) to ease its
passage through cable covering. It
may be desirable, perhaps even
necessary, to apply some silicon
grease to the outside of the new
liner so that it will slide easily
through the cable.
14. Insert the new piece of liner in the
conductor tube.
Note: If you found it necessary to
remove the gas and hose
connector at step 9, remember
to reconnect it after completing
step 12. The gas hose can be
reconnected by simply pushing
it into the back of the connector.
15. Insert the head of the gun liner
through the internal star lock
washer and the live wire terminal
(repeat the orientation noted in
step 9). With a 5/16 inch open end
wrench, screw the head end of the
new liner into the gas valve.
