Soldering Tools

Soldering iron tools are hand tools used in soldering. It supplies heat to melt solder so that it can flow into the joint between two workpieces. A soldering iron tool is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons less commonly used than in the past were simply a large copper bit on a handle, heated in a flame.
