(under subclass 36) Subject matter wherein the feed of at least one of the electrodes is accomplished by the consumption of the electrode material or by destruction by the heat of the discharge of obstructions to the motion of the electrodes.
(1) Note. Where the electrode is connected to source of power, as a mechanical or electrical motor, which transmits motion to the electrode to cause it to feed, the feeding is not considered to be of the consumption feed type although the loss in weight of the electrode due to the consumption of the electrode may effect the feed or control the operation of the source of power.
(2) Note. This subclass provides for discharge devices
having three or more electrodes, one or more of which are fed by consumption feeding and others of which are fed by mechanical means.
(3) Note. This subclass includes discharge devices having two or more of the electrodes placed so that the adjacent ends of the electrodes abut each other, the abutting electrodes acting in effect as a single electrode with respect to one or more other electrodes, the feeding of the abutting electrodes being accomplished by the consumption of either of the abutting electrodes.

59, for other consumable electrode discharge devices of the consumption feed type, and subclass 60, for electrodes limited by claimed subject matter to use with consumption feed-type consumable electrode discharge devices.
