ABSTRACT:
A new and improved thermal torch or lance useful in boring, cutting, burning, and the like, of hard base materials having a metal burner pipe with fusible wire or rod-like elements therein forming gas passages therebetween. The wire or rod-like elements are surface-pitted by oxidation or other means to cause turbulence within the transient gaseous oxygen stream caused to pass through the torch assembly is heated at the outlet end of the torch to cause an effectively concentrated thermic reaction with the metallic burner pipe and the associated rod-like elements. The result is an exceptionally efficient cutting temperature.
