Conventional welding rotators typically consist of a set of two or more rollers, including drive rolls and idler rolls. The drive rolls are motorized and provide the rotational force, while the idler rolls support and stabilize the workpiece. The workpiece is placed on the rollers, and the rotator rotates it, allowing operators to access all sides of the object for welding or assembly.
The rollers in a conventional welding rotator may have adjustable spacing to accommodate workpieces of different diameters. This adjustability allows for flexibility in handling cylindrical objects with various sizes.
