The Model 6 is a rugged, field-proven weld head for high-production welding of tube-to-tubesheet using the GTAW process. The Model 6 has exceptionally fast mount and dismount times for ease of operation and productivity. The torch is positioned on the tube to be welded by a pneumatically operated locating fixture. With the touch of a button, the locating fixture precisely locates itself over the tube to be welded. Rugged, reliable tube-to-tubesheet weld head with 200 A torch Welds projected or recessed tubes with filler wire, or flush joints without filler wire. Unlimited torch rotation Makes multiple-pass welds without stopping Self-supporting on tubesheet Air-operated fixtures speed up production Welds in any position, including overhead The “C” and “D” torches (for fillet welds) are spring-loaded torches with a chill follower. The chill follower is located on the inside of the tube to be welded and contacts the tube wall exactly opposite the electrode, thus minimizing the possibility of burn-through on thin-wall tubes. The mechanics of the spring-loaded torch allows it to perfectly track the shape of the tube regardless of minor ovality. The "E" torch is for welding flush or recessed tubes.
