    Abstract: A high pressure arc radiation torch provided with spaced tubular electrodes having axially aligned gas exit passages; an envelope of transparent material surrounding said electrodes in concentric relation and providing a pressurized gas chamber; one of said tubular electrodes extending into said chamber to form a relatively thin annular region substantially cylindrical in cross section between the outer surface of said tubular electrode and the inner surface of said chamber, and means for feeding gas into said annular region under conditions to provide strong swirl within the chamber resulting in a highly constricted arc column of substantial length.
