A ball bushing mounted carriage together with a feeding/return mechanism and a plasma torch is provided for cut-off of the finished tube. Upon command, the torch mechanism is pneumatically brought into cutting position with the pipe. A tool steel knife wheel mounted on the torch mechanism contacts the pipe, causing the cut-off machine carriage to follow the tube at equivalent horizontal speeds. Torch ignition is made and cut-off begins. Upon completion of the tube cut-off,the torch automatically shuts off. The torch mechanism is then pneumatically raised away from the pipe, and a carriage return to rest is initiated. A stanchion, for the torch position to be relative to the pipe diameter, is provided to insure that the torch is cutting at the best penetration and cutting angles. The carriage is constructed of aluminum for lightness, the base is fabricated steel, normalized and machined. The base of machine is equipped with horizontal and vertical screws for adjustments. Torch hose carriers are provided on the carriage.
