Abstract
The oxy-cutting torch comprises a support element (10) made from an undeformable block of stainless steel, and a heater element (20) permanently fixed against a bottom face (19) of the support element (10), which heater element is made from a solid block of copper in which passages are formed for gases and cooling fluid, which passages communicate directly with corresponding pipes of the support element (10). At least one nozzle (30) is positioned with precision in two bores (41, 32) in axial alignment provided respectively in the support element (10) and in the heater element (20), the nozzle being connected to a cutting oxygen feed pipe (14.6). A holder element (40) is preferably used to improve the precision with which the nozzle (30) is positioned.
