Abstract
A torch carriage assembly for use in bevel cutting a pipe has a ring gear which rotates concentrically about the pipe longitudinal axis. A shaft extending perpendicularly from the ring gear carries a torch arm block assembly which positions the cutting torch in relation to the pipe. A bracket is adaptable between a first configuration prohibiting and a second configuration permitting rotation of the shaft about its longitudinal axis for bevel cutting round pipes and out-of-round pipes, respectively. In the second configuration, a guide wheel assembly mounted on the shaft traces the surface of the pipe. A tension assembly continually urges the guide wheel assembly into contact with the surface of the pipe so that the angular position of the torch arm block assembly accurately reflects the out-of-round conditions of the pipe.
