Powerful and well-functioning self-set roller boom (welding switch) of the brand Wuxi Volcano Welding & Cutting Equipment. Ideal for rotation of tubes, cisterns and other cylindrical objects during welding, cutting or surface treatment. The set consists of a driven section and a fellow runner (idler). Because the model is self-set ("Self-alignment") the rollers automatically adapt to the diameter of the workpiece, saving a lot of time during conversions. The machine is equipped with a sturdy Ford Speed Reducer Co. (speed ratio 1:60) for a very high and stable torque. The speed is regulated steplessly via the transducer control system.
