What is the temperature of an electric soldering iron
The temperature of an electric soldering iron is 300-400 ℃.
Specifically, when direct insertion of electronic materials is required, the temperature of the soldering iron head should be set between 330 to 370 degrees. For surface mount materials, the appropriate temperature should be between 300 to 320 degrees. The repair of the buzzer requires a temperature of 270 to 290 degrees. The welding temperature of large component feet should not exceed 380 degrees. In addition, for special materials, special temperature settings are also required.
Electric soldering irons are divided into two types: externally heated and internally heated:
The externally heated electric soldering iron is composed of a soldering iron head, a soldering iron core, an outer shell, a wooden handle, a power lead, a plug, and other parts. Due to the installation of the soldering iron head inside the soldering iron core, it is called an externally heated electric soldering iron. The soldering iron core is a key component of an electric soldering iron, which is composed of electric heating wires wound parallel on a hollow ceramic tube, with mica insulation in the middle and two wires connected to a 220V AC power supply.
An internally heated electric soldering iron is composed of a handle, a connecting rod, a spring clip, a soldering iron core, and a soldering iron head. Due to the installation of the soldering iron core inside the soldering iron head, it generates heat quickly and has a high heat utilization rate. Therefore, it is called an internally heated electric soldering iron. The commonly used specifications for internally heated electric soldering irons are 20W and 50W. Due to its high thermal efficiency, a 20W internally heated electric soldering iron is equivalent to around 40W externally heated electric soldering iron.
The rear end of an internally heated electric soldering iron is hollow and used to connect it to the connecting rod, and is fixed with a spring clip. When replacing the soldering iron head, the spring clip must be removed first, and at the same time, the front end of the soldering iron head must be clamped with pliers, and slowly pulled out. Remember not to use too much force to avoid damaging the connecting rod.
What is the temperature of an electric soldering iron at 40W
The melting point of 40W soldering iron is approximately between 250 ° C and 300 ° C. The higher the power of an electric soldering iron, the higher the temperature.
