| 摘要 |
The invention relates to a plasma torch in which the position of the electrode (4) with respect to the orifice (11) of the plasma nozzle (5) can be adjusted. The electrode (4) is mounted on the body (3) of the torch via a ball-and-socket joint (14), whereby the electrode (4) can be rotated supported by the joint (14) thus facilitating the alignment of its tip in the center of the orifice (11) of the plasma nozzle (5). The ball part (14) of the joint is clamped in the socket (15) by means of a tightening bushing (16). The plasma torch electrode (4) is fixed to the pivotal joint (14) by means of a longitudinally adjustable assembly (12, 17, 20, 25), whereby the tip of the electrode (4) can be moved with the help of the adjustment assembly (12, 17, 20, 25) to touch the nozzle (5) thus effecting the alignment of the electrode in the pivotal support of the ball-and-socket joint (14) and under the guidance of the sliding tip of the electrode (4) to the center of the nozzle orifice (11).
