PURPOSE:To enable to perform instantaneously the change of a soldering iron by arranging plural soldering irons on the periphery of a freely rotatable bearing holder and by constituting these soldering irons vertically movably respectively independently. CONSTITUTION:A soldering iron 1a is withdrawn after performing a soldering with the feed of a solder from a solder feeding part 15 by abutting to a work 9 the soldering iron 1a which is held by a soldering iron holder 10 by descending the shaft 12 of a bearing holder 14. In case of the solder iron being worn or change due to the changing over of the kind of the article of the work 9 the soldering thereafter is performed by moving another soldering iron 16 onto the work 9 by rotating the holder 14. Even in case of the soldering of different conditions, the soldering is performed by selecting the optimal soldering iron with similar working. The equipment enabling to perform instantaneously the change of a soldering iron is thus obtd.
