Each threaded rod is mounted for rotational movement about its longitudinal axis in the end plates. One of the rods is adapted for operation by a power drill and the other is adapted for hand operation. A torch holder assembly, capable of vertical and angular adjustment, and adapted for receiving a cutting torch attached thereto, is mounted on the threaded rod for reciprocating lengthwise movement within the said channel.
