What is the temperature of the electric soldering iron? What is the temperature of the 40w electric soldering iron?
The temperature of the soldering iron is 300-400°C.
Specifically, when it is necessary to directly insert electronic materials, the temperature of the soldering iron tip should be set between 330-370 degrees. If it is a surface mount material, the temperature should be between 300-320 degrees. At a temperature of 290 degrees, the soldering temperature of large component feet cannot exceed 380 degrees. In addition, for special materials, special temperature settings are required.
There are two types of electric soldering irons: external heating type and internal heating type:
The external heating electric soldering iron is composed of a soldering iron tip, a soldering iron core, a shell, a wooden handle, a power lead, a plug and other parts. Because the soldering iron head is installed inside the soldering iron core, it is called an external heating type electric soldering iron. The soldering iron core is the key component of the electric soldering iron. It is formed by winding the heating wire in parallel on a hollow porcelain tube. The mica sheet in the middle is insulated, and two wires are drawn out to connect with the 220V AC power supply.
The internal heating electric soldering iron is composed of a handle, a connecting rod, a spring clip, a soldering iron core, and a soldering iron tip. Because the soldering iron core is installed inside the soldering iron head, it heats up quickly and has a high heat utilization rate. Therefore, it is called an internal heating type electric soldering iron. The commonly used specifications of internal heating electric soldering iron are 20W and 50W. Due to its high thermal efficiency, a 20W internal heating soldering iron is equivalent to a 40W external heating soldering iron.
The rear end of the internal heating type electric soldering iron is hollow, used to be sleeved on the connecting rod, and fixed with a spring clip. When the soldering iron tip needs to be replaced, the spring clip must be withdrawn first, and the front end of the soldering iron tip should be clamped with pliers. Pull it out slowly, remember not to use too much force, so as not to damage the connecting rod.
What is the temperature of a 40w electric soldering iron
The melting point of 40w soldering iron is about 250-300 degrees. The higher the power of the soldering iron, the higher the temperature.
