NOZZLE AND CONTACT TIP SYSTEMS

REMOVAL AND REPLACEMENT

Pull slip-on nozzles off with a clockwise twisting motion.

When installing nozzle, exposed insulator should nest inside shock

washer to assure concentricity.

Shock washers are positioned on the end of the gooseneck with

the large insulated counterbore facing the nozzle.

Replace nozzle retainer with deep counterbore toward the gooseneck.

Tighten until retainer and shock washer are secure.

THREAD-ON (OPTIONAL FOR TWECO HD)

Thread-on nozzle system does not require nozzle retainer and

cannot be used with heavy duty head.

Shockwasher must be in place.

External gooseneck thread can be cleaned with a 9/16"-18 die.

IMPORTANT

Shock washer must be in place before welding to maintain insulation of

gooseneck. Be sure all parts are tightened will before welding.

When using the heavy duty retaining head make sure it is tightened with

a 11/16" wrench to prevent overheating of contact tip.

To prevent scoring on heavy duty retaining head do not use pliers.

NOTE: Any of the above nozzle and contact tip systems can be used on the LIGHTNING
