6 2.0 MAINTENANCE 2.1 TREGASKISS NOZZLE AND TOUGH LOCK CONSUMABLES HEAVY DUTY NOZZLE VARIOUS SIZES AVAILABLE HEAVY DUTY TREGASKISS TOUGH LOCK CONTACT TIP HEAVY DUTY TREGASKISS TOUGH LOCK RETAINING HEAD NECK INSULATOR IMPORTANT: Neck insulator MUST be in place before welding to properly insulate gooseneck armor. Check all parts to ensure that connections are tight before welding. The retaining head MUST be tightened with a 5/8 (16 mm) wrench to prevent the contact tip from overheating. DO NOT use pliers to remove or tighten the retaining head or scoring may result. Removal and Replacement Nozzle Pull slip-on nozzles off with a twisting motion. When installing the nozzle, ensure that it is fully seated. Contact Tip Thread the contact tip into the retaining head. Torque to 30 in.-lbs. (3.5 Nm). The Tregaskiss Tip Tool (Part # for heavy-duty tips) or a pair of weld pliers are the optimal tools for contact tip installation. Retaining Head Thread retaining head onto neck with a 5/8 (16 mm) wrench. Torque to 80 in.-lbs. (9 Nm). DO NOT use pliers to remove or tighten the heavy duty retaining head or scoring may result. Neck Insulator The neck insulator is pressed onto the gooseneck by hand. 2.2 LINER REPLACEMENT NOTE: For guns equipped with power pins, Bernard, or Euro-connectors, the procedure is the same. On Miller style guns, liner is held captive by a guide cap, which must be removed and replaced when changing liner. STEP #1 CONDUIT LINER NOTE: Ensure power supply is off and gun is removed from feeder before proceeding. Remove nozzle, tip and gas diffuser and loosen liner from power pin using a 10 mm wrench. With gun straightened, grip conduit liner with pliers and remove. 6

Move the handle back. MOUNTING SCREWS HOUSING Crimp the support tube clamp. Crimp between the black and white switch leads. Position copper wires between roll marked numbers on cone and first step before threads. Crimp the large oetiker clamps 1/4 and 1 behind the outer jacket at the front of the torch. INNER TUBE CONNECTOR CONE NECK CONE NUT CONE NUT CONNECTOR CONE HANDLE Bend unicable behind connector cone, cut unicable at bend. Slide two large Oetiker clamps 1.5 ft. down the unicable (required for crimping later). From your cut (end of cable), measure 8 back, and cut away the outer jacket of the cable. **Be careful not to cut the copper wiring and leads**. Remove the inner gas tube from the cone. Fan out the copper and bring the copper around the inner gas tube evenly. CONE NUT OUTER JACKET BARE COPPER 7/8 (22mm) 3.5 (89mm) LEADS 8 (200mm) Slide outer jacket forward to expose the copper wiring and leads. Pull out the lead wires. From the 8 cut, measure 3 1/2 towards the front of the torch, and cut off the excess cable. Fan back copper, and remove 7/8 of the inner gas tube. Take the old liner you just removed, and cut it to approximately 2 ft. long. Thread cone onto vice mounted neck. Insert the 2 ft. of old liner into the neck from the front end of the neck, then slide on the support tube. Slide small Oetiker clamp over top of inner gas tube. Using the 2 old liner as a guide, slide the inner gas tube over the support tube and up to the cone shoulder. Slide the inner gas tube on the Cone up to the shoulder. Fan the copper evenly around the inner gas tube, up to the shoulder of the Cone Connector. Thread on the Cone Nut onto Connector Cone. Torque the Cone Nut to 30 ft.-lbs. (there should be about a 1/8 gap between the cone and cone nut). Using 3/4 Teflon electrical tape, wrap up the copper and spare switch leads neatly. Loop the 2 switch leads that will be used, this is to ensure that there is enough slack in the wire for gun articulation. Make sure that the control wire sheath is over switch leads where the cone and cone nut are to prevent any wear. Pull up the handle, and feed switch leads through handle. Strip leads about 1/8 back and crimp switch terminals to open leads. Connect the leads to the switch, and lay the switch back into the housing. Screw the switch housing back onto the handle.
