PLASMA CUTTING TORCH

PROBLEM TO BE SOLVED: To improve the assembly property by providing an inversely T-shaped projection on the inner side of a bent part of a torch body, engaging a torch body cover therewith and fixing it thereto, and connecting the torch body cover, a holding part and an insulation cylinder in a fitting manner to each other to avoid ingress of the detachment detection line of a shield cup into a connection part. SOLUTION: An inversely T-shaped projection 24 along a tip part from a root part is provided on the inner side of a bent part of a torch body 21, and a projection 28 on a forward part of a torch body cover 27 is engaged with an upper side to fix the forward part of the torch body cover 27 in the vertical direction. An insulation cylinder 25 is fixed in the upward direction and the torch body cover 27 is fixed in the forward direction by fitting a flange 26 at an upper end of the insulation cylinder 25 to a recess 29 in the forward part of the torch body cover 27. A projected part is formed on a lower part of a root part of the torch body 21, a detachment detection line 6 of a torch cup 5 is arranged in right and left spaces of the projected part, and held in the space between the inversely T-shaped projection 24 and the projection 28. In addition, the root part of the torch body cover 27 is fitted and fixed to a recess in a forward part of a holding part 30.
