DEVICE FOR PLASMA MACHINING OF METAL ARTICLES Russian patent published in 1995 - IPC

FIELD: vacuum engineering. SUBSTANCE: device comprises an extended anode and a cathode installed in a vacuum chamber, arranged coaxially with relation to each other and connected to power supply, and an electrode-igniting magnet; the ends of the anode are bent to opposite sides from cathode surface, the workpiece serves as the cathode, the magnet is elongated, is commensurable with the anode and is installed along the anode. The igniting electrode is installed between the cathode and the end of the anode bent towards the cathode. The anode is flexible and can be deformed to match the shape of the workpiece-cathode. EFFECT: improved design. 3 cl, 3 dwg
