  • Soldering iron and soldering apparatus
    Patent number: 4614295
    Abstract: The soldering apparatus of the invention includes a soldering wire feeding mechanism for feeding soldering wire from a storage spool. The soldering wire feeding mechanism includes a motor which drives a feeding wheel for engaging and transporting the soldering wire into a flexible feeding tube. An eccentric adjusting cylinder is mounted adjacent the wheel and can be turned to fit the diameter of the soldering wire being used. The feeding tube connects to the soldering iron of the invention, which has a metal guide tube through which the soldering wire extends and is fed to the soldering area. The soldering wire travels from the feeding tube to the guide tube through a sleeve to which both tubes are threaded. The free end section of the guide tube adjacent to the tip of the soldering iron extends rectilinearly from a bend or curve such that the soldering wire leaving the tube is rectilinear and not bent.
