Installation Instructions
1. Turn off power.
2. Remove nozzle, insulator, tip gas diffuser and neck from gun.
3. Remove old jump liner from the back end of the neck.
4. Insert new jump liner making sure the liner stop is fully seated at back end of neck.
5. Take the tapered end of the neck and insert into the end fitting of the gun handle. Make sure that the liner extruding from the
