The temperature of the soldering iron is 300-400 degrees Celsius.
Specifically, when it is necessary to insert the electronic material directly, the temperature of the soldering iron head should be set between 330-370 degrees, if it is a surface mount material, the temperature is suitable between 300-320 degrees, the buzzer repair needs a temperature of 270-290 degrees, and the soldering temperature of the large component feet should not exceed 380 degrees, in addition, for special materials, it is necessary to set the temperature specially.

The externally heated soldering iron consists of a soldering iron head, a core, a shell, a wooden handle, a power lead, a plug and other parts. As the iron head is installed in the iron core inside, so it is called the external heat type iron. Soldering iron core is the key component of the soldering iron, it is the electric wire parallel winding in a hollow porcelain tube composition, the middle of the mica sheet insulation, and lead to two wires and 220V AC power supply connection.

The endothermic soldering iron consists of a handle, connecting rod, spring clamp, soldering iron core, soldering iron head. As the iron core is installed inside the iron head, it generates heat quickly and has a high heat utilisation rate, so it is called an endothermic soldering iron. The common specifications of endothermic soldering iron are 20W and 50W. Due to its high thermal efficiency, 20W endothermic soldering iron is equivalent to about 40W exothermic soldering iron.

Soldering iron 40w is how much temperature
Soldering iron 40w solder melting point is about 250 degrees -300 degrees between. The higher the power of the soldering iron, the higher the temperature.
