How many watts is suitable for household soldering iron
The power and temperature of an electric soldering iron are not closely related. The higher the power, the larger the solder joints that can be soldered. Some soldering parts that conduct heat quickly also require a high-power soldering iron. According to the formula: heat=power * time, the higher the power, the shorter the time it takes for the soldering part to reach the same heat, and it 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. There are also many specifications of electric soldering irons according to their power under these two classifications. For external heating type, the higher the power, the higher the temperature of the soldering iron tip, while the power of internal heating type is different from that of external heating type.
There are two main types of soldering irons: internal heating and external heating. There are several types of internal heating electric soldering irons, including 20, 30, 35, 45, 50, and 75W. In addition to the wattage of internal heating soldering irons, there are several other types of external heating soldering irons, such as 100, 150, and 300W. Selection of internal and external heating: Under the same wattage, the temperature of an internal heating soldering iron is higher than that of an external heating soldering iron.
Electric soldering iron is the most commonly used welding tool in wire harness related welding operations. Its function is to convert electrical energy into thermal energy to heat and weld the welding point. The success of its operation largely depends on how it is controlled. Therefore, from a certain perspective, the use of an electric soldering iron relies on a sense of technique.
Generally speaking, the choice of soldering iron is the choice of soldering iron power. The power of an electric 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 selected electric soldering iron should have a higher power.
30W: Suitable for mobile phones MP3, Waiting for products with small solder joints
40W: Suitable for Little Overlord game controllers, handheld game consoles, etc
60W: Suitable for household appliances such as televisions, speakers, keyboards, recorders, radios, fans, game joysticks, etc. Simultaneously covering all appliances suitable for 30W and 40W. Can repair all household appliances universally.
