  • Patent number: 5893992
    Abstract: A portable electric soldering tool includes a housing forming a handle and a power head. A heating rod extends from the power head, the rod having an axial bore with a stainless steel lining to prevent solder from building up in the heating rod. A heating coil heats the heating rod. The heating rod directs melted solder into an extraction tube in which a curved wafer is disposed to collect the solder. A diaphragm pump is mounted in the power head and has an oblong piston head, which is mounted with the long axis aligned on a longitudinal axis of the tool, which facilitates a more compact unit.
