ABSTRACT:
A method of attaching fine coil wire ends 22, 24 to terminal connectors 16, 18 wherein the terminals are rapidly heated into the red zone by common current flow therethrough from contact electrodes 26, 28 in the presence of a gaseous purge comprising a mixture of hydrogen balance argon, nitrogen, or helium while low melting temperature solder 84 is flowed onto the heated terminal for wire attachment. The gaseous purge from a nozzle 80 is maintained until the terminal has cooled sufficiently to prevent rapid atmosphere oxidation thereof.
