Abstract
A method is provided for soldering a coil winding to a terminal pin. A specific quantity of solder is applied onto the terminal pin, the terminal pin having a winding end wrapped therearound. The solder, for example, can be applied by immersing the pin end into a solder bath having a temperature only slightly above the melting point of the solder. Subsequently, the solder is melted with a welding torch under a protective atmosphere only at a power and time required to achieve a soft-soldering temperature. As a result thereof, a soldering free of fluxing agent and without the high thermal stress of a welding is possible. Other embodiments include placing a ring of solder onto the terminal prior to heating. Also, a predetermined length of solder wire can be brought into contact with the terminal pin prior to heating. The invention provides a guide tube device for such a purpose.
