PROBLEM TO BE SOLVED: To provide a soldering iron, which is used in a device that feeds a constant amount of solder to a cylindrical guide to automatically perform soldering, capable of easily soldering a non-horizontal surface to be soldered.SOLUTION: A soldering iron comprises: an iron tip including a guide tube inside for feeding solder; and heating means to provide heat to the iron tip. The guide tube comprises: a solder feeding part disposed in an upper part; and a solder discharging part disposed at least in one part of a side face in a lower part, and feed molten solder through the solder discharging part to vertically solder a horizontally placed pin so as to appropriately apply a constant amount of solder to the horizontally placed pin on a vertically arranged substrate.SELECTED DRAWING: Figure 2 |
