ABSTRACT:
A method and apparatus for brazing a commutator to a pair of armature wires which are arranged one above the other employ a dual brazing alloy wire feeder which feeds one brazing alloy wire between a commutator and the lowermost armature wire, while simultaneously feeding the other brazing alloy wire between the lowermost armature wire and the uppermost armature wire. At the conclusion of the brazing operation, the partially consumed brazing alloy wires are automatically advanced to a predetermined length in preparation for a subsequent brazing operation by which the commutator is mechanically and electrically connected to another pair of armature wires.
