ABSTRACT:
A fluid cooled cutting torch includes a hollow handle, a torch butt assembly, a torch head, supply tubes for preheat gas, preheat oxygen and cutting oxygen and cooling fluid supply and drainage conduits. The torch head is adapted to interchangeably receive a premix or postmix cutting torch nozzle. The cooling supply conduit extends through the torch butt assembly and within the torch handle to a point adjacent the torch head. The cooling system provides effective cooling of the torch head and even cooling of the torch handle. The torch is easily manufactured at low cost. The torch may be readily converted from a premix torch to a postmix torch.
