5. Push liner back into gun and hold in place. Using liner gauge,
trim liner to a 3/4” stick-out.
HELPFUL HINT: Before cutting liner, make a mark after the gauge
and pull it back out past the end of the welding wire; then cut it and
push the liner back into place securely. This will help with feeding
the wire through the contact tip afterwards.
6. Remove any burr that may obstruct wire feed.
7. Reinstall consumables onto neck.
B. Changing QUICK LOAD Liner in the AutoLength System
NOTE:
Ensure power supply is off before proceeding.
1. Remove consumables (nozzle, contact tip and retaining head) (see
Section 4-1 Changing Consumables
).
2. Remove existing QUICK LOAD Liner by pulling it out from the neck.
3. Insert the new QUICK LOAD Liner through the neck using the welding wire as a guide
(short strokes will prevent kinking).
4. Feed liner into the gun until it engages with the retainer inside the AutoLength Pin. Place the liner gauge onto the end
of the QUICK LOAD Liner and press flush with the end of the neck.
5. Push the QUICK LOAD Liner into the gun until the liner will not go forward any further.
NOTE:
Liner will be pushed in
by approximately one additional inch.
6. Using the liner gauge, trim the liner with 3/4” (20 mm) stick out.
NOTE:
After trimming, the liner will stick out of the
neck by approximately 1 3/4”. This is normal, as the liner will be pushed back into the neck when the consumables
are installed.
7. Feed wire through the MIG gun.
8. Reinstall consumables.
