E-HEAD WELD HEAD Model 441A Orbital Weld Heads for Fusion/Filler Wire Welding of Tube and Pipe Use with Tubemaster Model 514A Power Source
Precision Tools for Precise, Repeatable Welds
The E-Head is specifically designed for welding light wall pipe. It is the answer for the fabricator or contractor that must weld a wide size range, normally requiring the purchase of multiple weld heads. The E-Head can be used on any size pipe from 25mm (1") to 356mm (14"), with the change of only one mounting component. The E-Head consistently produces welds meeting the most stringent code quality standards and is ideal for applications with limited radial clearance. The E-Head clamps on only one side of the joint, allowing use for pipe-to-fitting welds. Ideal for orbital tube welding. The E-Head incorporates a mechanical arc length control device to compensate for out-of-round pipe. For welds requiring filler wire addition, an optional wire feeder can be mounted on the weld head. A standard wire spool mounted directly on the Head provides precise and positive wire feeding, not possible with floor-mounted feeders.
