(under subclass 130) Devices having an electrical impedance supported by the discharge device structure.
SEE OR SEARCH THIS CLASS, SUBCLASS:
13, and 14, for consumable-electrode discharge devices having an impedance which is placed in shunt circuit about the discharge device when the electrode is consumed or fails to maintain the discharge.
113, and indented subclasses, where the impedance is the coil of the separating and/or feed control electromagnet.
