Testing and Changing the Liner
Should feeding problems occur, the first item to be check
should be the liner. The following check should be made to
determine is the line is defective:
1. Fee 12’ to 18" of fresh wire out of the welding fun.
(See Fig. 17.)
2. Disconnect the welding gun from the machine with
the wire still threaded in the gun. Pull the gun 6"
away from the machine and clip the wire so that 6"
of the wire is extending out of the welding gun.
(See Fig. 18.)
3. Push the wire in and out of the welding gun as
shown in Fig 19. The wire should move freely in the
gun with little or no resistance. If there is a great
deal of friction, the liner should be replaced.
To replace the liner, loosen the allen screw which is accessible
through a small hole in the handle of the welding gun. Remove
the liner positioner nut with a 12mm wrench and pull the old
liner completely out of the welding gun (See Fig. 20). Remove
the gas nozzle and contact tip. If installing a Teflon liner, install
the collet on the liner. If the liner has plastic insulation on it, it
is important that the plastic insulation is stripped back at least
2 feet from the front end of the welding gun. Slowly push the
new liner into the welding gun. (See Fig 21.) Be careful not
to try to push too much liner into the gun at one time, or the
liner may kink. Lay the welding gun out straight and install the
liner positioner nut. Clip the excess liner off flush with the end
of the swan neck. Use a razor blade on Teflon liners. (See Fig
22.) Install the correct size contact tip. The contact tip should
butt into the end of the liner.
