Model 6 Weld Head

Model 6 Weld Head

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.
