DEFINITION

Classification: 314/4

(under subclass 1) Subject matter wherein a consumable electrode discharge device is provided with a plurality of cathodes and/or anodes, two or more of the electrodes being movable, the movable electrodes being operated by means of the same motive power means.

(1) Note. In most of the devices in this subclass, one of the movable electrodes is held stationary while the first operated electrode is fed to the discharge, and means are provided for automatically releasing the stationary electrode so that it may be actuated by the feed regulating mechanism when the first operated electrode is consumed or fails to operate.

(2) Note. Continue the search in subclass 3 of this class.
