Simple irons reach a temperature determined by thermal equilibrium, dependent upon power input and cooling by the environment and the materials it comes into contact with. The operating temperature of these irons is not regulated directly gas irons may change power by adjusting gas flow. Small irons heated by a battery, or by combustion of a gas such as butane in a small self-contained tank, can be used when electricity is unavailable or cordless operation is required. Simple irons run at an uncontrolled temperature determined by thermal equilibrium when heating something large their temperature drops a little, possibly too much to melt solder.

Some irons are temperature-controlled, running at a fixed temperature in the same way as a soldering station, with higher power available for joints with large heat capacity. Higher ratings are available, but do not run at higher temperature instead there is more heat available for making soldered connections to things with large thermal capacity, for example, a metal chassis. Less common uses include pyrography (burning designs into wood) and plastic welding.įor electrical and electronics work, a low-power iron, a power rating between 15 and 30 watts, is used. Large irons may be used for soldering joints in sheet metal objects. High-volume production lines use other soldering methods. Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. Simple irons less commonly used than in the past were simply a large copper bit on a handle, heated in a flame.

Portable irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element.

It supplies heat to melt the solder so that it can flow into the joint between two workpieces.Ī soldering iron is composed of a heated metal tip and an insulated handle.
