ABSTRACT:
Methods and apparatus for fusing together electrical conductors to a commutator are provided. A precise, timed, and controlled delivery of electric current to the fusing electrode of the fusing machine is achieved. A generic supply signal is converted into a precise and constant input signal through the use of monitoring and feedback techniques, which compare the current status of the physical and electrical phases of the fusing operation to various predetermined fusing profiles to determine the proper application of current to the fusing electrode.
