How To Change a Conventional Liner on a TOUGH GUN Robotic MIG Gun Equipped with Wire Brake

 


STEP 1:

  • Unthread and remove the liner from the back of the MIG gun.

STEP 2:

  • Insert the new liner from the back of the torch. The liner will bottom out on the Wire Brake.
  • Measure the distance from the back of the power pin to the hex on the liner and take note of the measurement.


STEP 3:

  • Remove the liner and cut the length of your measurement off the front of the liner.

 


STEP 4:

  • Reinsert the liner and tighten with a 10-mm wrench.
  • Remove the neck and pull out the jump liner (item #27).


STEP 5:

  • Reinsert a new jump liner into the neck and install the neck back onto the torch.
  • Push back on the jump liner to make sure that it has seated properly against the Wire Brake and cut so that a 1/2 inch of the liner is sticking out of the neck.
