How To Change a Conventional Liner on a TOUGH GUN Robotic MIG Gun Equipped with Wire Brake
To change a conventional liner on a TOUGH GUN® robotic MIG gun equipped with wire brake, follow the instructions below:
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.
