ABSTRACT:
A miniature light-weight electric soldering iron includes a hollow handle terminating in a conical air deflecting arrangement through which a cone-shaped curtain of relatively high velocity air is applied to the work area in a circular or elliptical region surrounding the point at which molten solder is being applied by the hot soldering iron tip thereby entraining and dissipating noxious fumes which may be generated from the soldering flux by the hot soldering iron tip. In one embodiment, the soldering iron handle is provided with a plurality of wall air inlet openings and a tiny motor and fan are incorporated to draw air into the handle through these openings and then direct it out through a truncated cone-shaped deflector to develop the air curtain. In another arrangement, the motor and fan are dispensed with and the cone-shaped deflector is coupled to a convenient pressure source, such as an air line. The flow of air further serves to maintain the handle at a comfortably cool temperature.
