ABSTRACT:
A torch having a body carrying valves for controlling the flow of fuel and oxygen, with a conduit structure projecting from the body and carrying a two-section swiveling head assembly mounting a nozzle for swinging movement between different angular settings. The two hinge sections are both made relatively short as compared with the length of the conduit structure, in a relation enabling optimum adjustment of the angularity of a produced flame within a wide range of angles, without excessively displacing the actual position of the flame relative to the body of the torch and a work piece. One of the hinge sections is preferably attached rigidly to the conduit structure, and is made small enough in transverse dimension to enable an outer tubular housing part to be received about and moved axially past that hinge section during assembly, to a location about the mentioned conduit structure.
