Soldering, rework and desoldering irons and stations include stations, accessories and power supply units necessary for soldering applications. Stations are units comprised of the key components of a soldering operation: power supply and regulation, soldering iron, iron stand and sponge. Soldering irons consist of a heated metal tip at the end of an insulated handle. The tip is most commonly heated by electrical power, then applied to melt the solder. When the soldering iron is part of a soldering station, the heat is regulated through the station.
