DEFINITION

Classification: 314/113

(under the class definition) Subject matter provided with (1) an electromagnet for supplying the energy for separating an electrode, or (2) with an electromagnet which controls the operation of the feeding mechanism.

(1) Note. Continue the search in subclasses 67, 70, 77, and 90 of this class.

SEE OR SEARCH THIS CLASS, SUBCLASS:

67, 77 and 78, for consumable electrode discharge devices having an electromagnet for supplying the energy for moving the electrode in the feeding direction.

41, 61, 70, 72, 73, and 79 and indented subclasses, for consumable electrode discharge devices provided with

electromagnetic means for controlling the operation of mechanism which feeds the electrode by positively moving the electrode.

82, 83 and indented subclasses, 90, 93 and 112, for consumable electrode discharge devices provided with electromagnetic means for operating mechanism to release the consumable electrode from its holding means so that the electrode may be moved in the feeding direction. SEE OR SEARCH CLASS
