NON-TRANSFERRED AND HOLLOW TYPE PLASMA TORCH

A plasma torch includes a rear torch unit and a front torch unit which are connected through an insulating body. The insulating body is made of an insulator, is injected with gas required to generate plasma, and includes an inflow chamber that may move the injected gas. The rear torch unit coupled with a rear side of the insulation body communicates with the inflow chamber and has a magnetic coil generating a magnetic field within a cavity of the rear electrode wound around an outer circumferential surface thereof. The front torch unit disposed at a front side of the insulating body so as to face the rear torch unit communicates with the inflow chamber of the insulating body and has the front electrode disposed therein. The front torch unit does not include a magnetic coil winding the front electrode, and thus may be easily detached from the insulating body.
