The power of the electric soldering iron has little relationship with the temperature. The higher the power, the larger the solder joints that can be soldered. Some soldering parts that conduct heat faster should also use a high-power soldering iron. According to the formula: heat = power * time, the higher the power, the better It is said that the shorter the time for the weldment to reach the same heat, has nothing to do with the set temperature of the soldering iron. At present, electric soldering irons are mainly divided into two types: external heating type and internal heating type. Under these two categories, there are also many specifications of electric soldering irons according to different power. For the external heating type, the higher the power, the higher the temperature of the soldering iron tip, and the power of the internal heating type is different from that of the external heating type.
There are two types of soldering irons: internal heating and external heating. There are mainly 20, 30, 35, 45, 50, 75W types of internal heating soldering irons. In addition to all the wattages of the internal heating type, there are 100, 150, 300W and so on. Choice of internal heating and external heating: Under the same wattage, the temperature of the internal heating iron is higher than that of the external heating iron.

Soldering irons are the most commonly used soldering tools in wire harness-related soldering operations. Its function is to convert electric energy into heat energy to heat and weld the welding point. A large part of its success depends on how it is controlled. Therefore, from a certain point of view, the use of an electric soldering iron relies on a sense of technique.
Generally speaking, the choice of electric soldering iron is the choice of electric soldering iron power. The power of the soldering iron should be determined by the size of the soldering point. The area of the soldering point is large, and the heat dissipation speed of the soldering point is also fast, so the power of the soldering iron should be larger.
30W: suitable for mobile phones, MP3, and other products with small solder joints
40W: suitable for Xiaobawang gamepad, handheld game console, etc.
60W: Suitable for TVs, stereos, keyboards, tape recorders, radios, electric fans, game joysticks and other home appliances. At the same time, it covers all electrical appliances suitable for 30W and 40W. Able to repair all household appliances.
Some high-current solder joints require a lot of tin. If the power is too low, the heat will be dissipated too quickly, and the solder joints will not be easily tinned or appear semi-liquid. In this case, it is easy to produce gray tin and false soldering. The disadvantage of high-power soldering iron is that it has a short lifespan, cannot be powered on for a long time, is relatively troublesome to maintain, and is easy to burn components and boards if the technology is not good. So choose a soldering iron with the right power according to your own requirements.
