ABSTRACT:
An electrically heated soldering tool for gripping and heating joints that are to be soldered together, includes a pistol-grip case having a stationary upper jaw and a pivotable lower jaw extending from the front end thereof. The jaws have confronting portions shaped to closely grip the work and are each provided with an electric heating element for heating the confronting portions of the jaws. The jaws are detachably secured to the case by prong and socket connections. An air duct in each jaw communicates with air outlet openings in the confronting portion of the jaw and a motor-driven fan is provided in the case for selectively directing air through the ducts and outlet openings, whereby, dependent on whether or not the heating elements are energized, either heated air or cool air can be directed against the work to heat or cool the work.
