ABSTRACT:
A cutting torch is provided circumjacent its tip with a stand-off cup which maintains a fixed distance between the torch orifice and the work piece.

Between the notches are posts or castellations, at the distal end of which is a ring that maintains constant spacing between the cutting arc and a template, as the torch is guided around the edge of the template.
