Soldering iron
hand tool used in soldering
A soldering iron is a device used for attaching wires and electronic components together with solder (usually a mixture of tin and lead). This action is called soldering. They can also be used for other tasks such as fixing jewelry. There are several different kinds of soldering irons, such as ones that make use of transformers, or ones that heat up to higher temperatures than others. Some even use natural gas.
A soldering iron stand can be used to hold the iron. It is usually a flat metal stand with a coil that holds the iron.
