Nozzles:
1. If anti-spatter is used, do not coat nozzle insulator as this
may degrade insulating material.
2. Nozzle should be cleaned as often as possible. Spatter
buildup can often lead to poor gas shielding or short circuit-
ing between the contact tip and the nozzle.
3. Spatter should be removed with the proper tools designed
for spatter removal.
4. In high temperature welding applications, heavy duty con-
sumables are recommended.
Contact Tips, Gas Diffusers:
1. Contact tips may be removed and rotated in gas diffuser,
providing an additional wear surface and extending the
service life of the product.
2. Inspect nozzle for spatter adhesion, blocked gas ports, and
carburized contact surfaces. Clean as often as possible.
3. If anti-spatter is used, periodically check gas ports for block-
age.
4. When using dual shield electrode, periodically check gas
ports in gas diffuser for clogging caused by flux from within
the electrode.
Cable:
1. Periodically check torques of neck and end fittings. Loose
fittings can cause overheating and premature failure of the
gun.
2. Sharp bends and loops in the cable should be avoided. Often
the best solution is to suspend the wire feeder from a boom
or trolley, thus eliminating a large number of bends and
keeping the cable clear of hot weldments.
3. Do not immerse liner into solvents for cleaning; the liner
may be periodically blown out with compressed air.
4. Avoid rough surfaces and sharp edges that can cause tears
and nicks in cable jacket which can cause premature failure.
5. Periodically check all cables and ground connections.
6. Use anti-seize on all threaded connections.
Part III Helpful Operating Tips
Feeder:
1. Check drive rolls for wear; be sure drive rolls and guide
tubes are clean and free of debris. Do not overtighten drive
rolls; set as per manufacturer’s specifications.
2. Use clean, non-corroded electrode.
3. When installing or replacing electrode, you may: remove
burrs from end of electrode, remove head/gas diffuser and
contact tip, and/or straighten the first few inches of elec-
trode.
