ABSTRACT:
An improved guide for cutting-off and/or bevelling pipe with a torch using a ring-shaped member with circular guide-surfaces fixed around the pipe, includes the ring-shaped member circumference forming axially spaced first and second rim-and-ledge tracks engaged respectively by wheels of frame-mounted outer bogies; inner bogies positioned for running on the inner surface of the ring mount to the outer bogies resiliently to accommodate irregularities in the tracks; the frame has first and second ends for holding torch-carrying depth-adjustment mechanisms with the torch respectively at 37 degrees to the axis of the work and at 90 degrees to the axis of the work, as selected; provisions permitting rotation of the torch about the flame axis and quick attachment-detachment of the torch are disclosed.
