"Vintage Machinery" entry for Weller Electric Corp.
Description:
Reissue of the original soldering-gun patent. The main purpose of the reissues is to emphasize that the soldering tip receives a disproportionate amount of the heat because of its smaller cross-section compared to the secondary windings and the "forward extensions" that form the barrel of the soldering gun.
