ELECTRODE UNIT OF PLASMA TORCH Russian patent published in 1994 - IPC

FIELD: plasma metal working. SUBSTANCE: unit has electrode holder, removable electrode, channel for the cooling liquid, pipe and two-step bush. The bush step of less diameter is located from the side of the dead end of the axial channel. During the liquid passage the pressure differential between the upper and the lower parts of the channel divided by the bush takes place. Owing to that the pipe is self-adjusted into a working position resulting in intensifying the electrode cooling. EFFECT: facilitated manufacture. 1 dwg
