[0002] Electric soldering iron is an essential tool for electronic manufacturing and electrical appliance repair. Its main purpose is to solder components and wires. According to its mechanical structure, it can be divided into internal heating type and external heating type. According to its function, it can be divided into non-desoldering type and desoldering type. According to its use, it can be divided into high-power type and low-power type. Usually "solder wire" is used as flux, and the solder wire generally contains rosin for flux.

[0003] An electric soldering iron usually consists of a soldering iron tip, a soldering iron core, a shell, a handle, a power lead and a plug. The soldering iron core is a key component of the electric soldering iron. It is composed of a heating wire wound in parallel on a hollow porcelain tube. The mica sheet in the middle is insulated, and two wires are led out to connect to a 220V AC power supply. Commonly used ones are 25W, 45W, 75W, 100W, etc. The greater the power, the higher the temperature of the soldering iron tip.
