R-SERIES WELD HEADS
Models 427A, 428A, 429A
Orbital Weld Heads for Fusion/Filler Welding of Tube and Pipe
Use with Tubemaster Model 514A Power Source
Precision Tools for Precise, Repeatable Welds
The R-Head series of weld Heads are easy-to-operate tools for welding pipe. Three standard models cover pipe sizes 12.7mm to 168mm OD (0.5" to 6.625"). A mechanical arc length control device compensates for out-of-round pipe. The basic weld Heads can be used for fusion welding applications. Filler wire feed modules are optionally available for all models.
The Second Generation design provides continuously adjustable clamping - no need to interchange components when changing pipe sizes.
R-Heads clamp only on one side of the weld joint, allowing use for pipe-to-fitting welds.
Used with all all Tubemaster and Pipemaster models, these weld heads improve productivity by increasing duty cycle, reducing repair rates and producing welds of consistent quality.
MOUNTING The Weld Head mounts entirely on one side of the joint, allowing use on pipe-to-pipe and pipe-to-fitting welds.
