ABSTRACT:
A soldering iron for withdrawing by suction resin-containing soldering fumes includes an electric heating element (2) enclosed in a metallic casing and extending from one end of a handle (1), a metallic fume suction nozzle (6) has one end (7) lying in proximity to a soldering tip (5) mounted to the outer end of the heating (2) and its other end (8) connected proximate the one end of the handle to the first end of a flexible plastic e.g., silicone polymer; suction hose (10) removably extending through a bore (15) in the handle (1) and connected at its other end to suction source (11). The nozzle (6) is coupled in metallic heat transfer contact with the casing of the heating element (2) by metallic member (12, 13) and is thereby maintained at a temperature such that resins present in the fumes do not precipitate in the nozzle (6) but instead condense in the plastic suction hose (10), which can be easily removed from the handle for cleaning. The exterior surface of the plastic hose (10) within the bore (15) may be cooled by air drawn through the bore by the suction source (11) to promote condensation of the resins therein.
