摘要： A plasma torch has a torch body provided with a plurality of stacked torch body segments disposed between a rear electrode unit and a front electrode unit. The torch body forms a circular channel through which gas flows in an axial direction. Each torch body segment has a circular disc shape in which a central circular through-hole is formed to form the channel. Each segment includes gas supply ports defining a spiral-shaped flow path along the through hole on a first side of the segment so as to introduce a reactive gas, a cooling flow path, a cooling water supply flow path, a cooling water discharge flow path, a gas supply flow path, a gas branch flow path, a cooling water supply branch flow path, and a cooling water discharge branch flow path.
