A component of the electrical circuit that terminates at the arc, molten conductive slag, or base metal. See also ELECTRODE MANUFACTURE, CUTTING ELECTRODE, TUNGSTEN ELECTRODE, STAINLESS STEEL and WELDING ELECTRODE.

Metal Arc Electrode. Filler metal in the form of a wire or rod, either bare or covered, through which current is conducted between the electrode holder and the arc.

Carbon Arc Electrode. A carbon or graphite rod through which current is conducted between the electrode holder and the arc.

Atomic Hydrogen Electrode. One of two tungsten rods between the points of which the arc is maintained. See ATOMIC HYDROGEN WELDING.

Resistance Welding Electrode. The part or parts of a resistance welding machine through which the welding current and the pressure are applied directly to the work. See RESISTANCE WELDING.
