A tool used to melt solder for joining metal parts, especially in electronics work.
I use a soldering iron to attach components to the circuit board.
Be careful, the tip of the soldering iron is hot.
Rarely used kanji form; 鏝 is a non-jōyō character.
Compound of 半田 (はんだ, 'solder') and ごて (鏝, 'trowel; iron'). The word 半田 itself is of uncertain origin, possibly from a historical term for solder.
