ABSTRACT:
An electric soldering iron is disclosed in which a gas such as compressed air is electrically heated and then forced through a metallic soldering tip which is deeply slotted or finned for maximum heat transfer thereto. Soldering is then accomplished by applying the thusly heated tip to the workpiece. The slots may be formed to exhaust the hot gas forwardly over the tip to add heat to the workpiece and control the gaseous environment thereof; or the slots may be formed to exhaust the hot gas laterally or rearwardly to help in removing pollutants from the operator's environment.
