Rotary Torch Circle Welder (Welda-round)
Rotary welding machines are systems designed to weld circular components with high through-put. These machines offer both single or multiple torches to weld both small and large surface areas.
The BANCROFT WELDA-ROUND family of automated are versatile and durable production tools designed to weld a broad range of parts. They are designed to economically satisfy your production needs without the added costs of highly engineered systems. These rotary welders are also commonly referred to as: fitting welders, circle welders, header welders or port welders.

550 WeldA-Round
The concept of the 550A was to remove as much friction on the aluminum wires as possible to alleviate feeding issues on a Welda-round type machine. It’s a rotary torch machine with a unique design allowing feeding of aluminum by rotation the feed motor, welding torch, and standard aluminum wire spool with the spindle during welding

600 WeldA-Round Circle Welder
BANCROFT’s dual arc technique provides unbeatable advantages for users who require speed and quality above all else. With the MODEL 600 Fitting welder, arc time is reduced by half due to the rotating torches, each traveling 180 degrees plus an adjustable overlap. Part distortion is greatly reduced or eliminated by starting the welds 180 degrees apart. Setup and tooling are simplified by rotating the torches rather than the workpiece.
