Abstract
A plasma gas is injected from a vortex flow forming hole defined to an insulator in a tangential direction with respect to the circumference of the arc column of a torch to enable the axis of the arc column to be aligned with the axial of the torch and a vortex annular gas sheath is coaxially formed to thereby narrow down a plasma flame. Further, the torch comprises the above insulator and a casing which are connected in series each other.
