Soldering is the process of holding to items together with solder. This process can be done in many ways including a soldering iron. The end or tip of the iron provides the heat to the items you want soldered and the solder. The heated metals will hold the solder better then cold metals.

An electric soldering iron is used for wires and boards in electronical equipment. Computer boards and switch boards for appliances are where these soldering irons are used the most. These soldering irons can be powered by electricity and are generally low in energy. They are usually in the range of 15 to 30 watts.

Small battery powered soldering irons are available if you need to repair something where there is no electricity. These portable irons are very useful in certain situations. They are handy to get into tight spots and you do not have to fight a cord.

Electric soldering irons can also be used to solder wires together. A soldering iron is safely used where open flame might cause a fire.
