Abstract: An electric soldering iron is disclosed incorporating a front end to provide a heated working tip, the elongate, somewhat cylindrical structure of the tip defining an annular groove to receive a ring for retaining engagement with a threaded collar. The portion of the front end remote from the tip terminates in a radial-flange fastener structure which is affixed to the ends of a pair of elongated handle members that mate together to define a somewhat symmetrical handle, having an irregular internal passage for anchoring the cord (energizing electrical conductors) and relieving stress. As disclosed, a pair of sliding collars are disposed on the handle members for locking the assembly together. One of the collars (adjacent the front end) is internally tapered and defines ridges to engage the handle members so as to provide air spaces for heat shielding and insulating the handle. The handle defines corners as a result of a triangular sectional configuration to inhibit rolling from a rest position.
