Step 13
The steel cable sticking out the back of the gun with the hose and wires is your
liner, this is what guides your welding wire to the tip of the gun and you will need
to trim this to fit in the wire feeder. The liner should reach as close to the drive
roll as possible without touching it, use your previous gun as reference to trim it.
Once
the liner is trimmed to the correct length you can then set the gun end and
liner in place and replace the cover (the one with 4 screws that you removed at
the beginning of this walk-through) that holds your gun to the wire feed
mechanism. The liner and gun must remain in their intended grooves or your
machine will not function properly. This can be tricky and can be made easier by
laying the machine on its side (wire feed side facing up).
