ABSTRACT:
A plasma arc pipe cutting apparatus incorporates a plasma arc torch adjustably coupled to a motor-driven ring which transports the torch in an orbit about the pipe to be cut. The apparatus includes a pipe clamping fixture allowing the pipe to be cut to be concentrically mounted within the ring so that the gap between the electrode of the plasma arc torch and the work piece remains constant through the orbital travel of the torch.
