Abstract
A method of and a device for metering a solder wire to a solder location in which an electric motor for driving solder wire feed means supported on a carriage of a solder wire metering device is actuated to provide for feeding a predetermined length of the solder wire to a soldering location, a magnitude of a mechanical feed force appliced to the solder wire is controlled in proportion to a magnitude of a contact pressure force acting on an end of the solder wire at the soldering location, and the electric motor is stopped after the predetermined length of the solder wire has been melted.
