What types of common electric soldering irons are there?
Regarding the knowledge of electric soldering irons, there are different classifications of electric soldering irons, mainly including external heating electric soldering irons, internal heating electric soldering irons, constant temperature electric soldering irons, and tin-absorbing electric soldering irons. Different electric soldering irons have different structures and tips. Let's take a look at it in detail.
Classification of electric soldering iron
There are many types of electric soldering irons. Commonly used electric soldering irons are divided into external heating type, internal heating type, constant temperature type and tin suction type.
1. External heat soldering iron
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, etc. It is named because the soldering iron tip is installed inside the soldering iron core, as shown in the figure below.

The tip of the soldering iron is generally made of copper material, and its function is to store and conduct heat. When in use, the temperature of the tip of the soldering iron must be higher than the melting point of the object to be soldered.
The temperature of the soldering iron depends on the size, shape and length of the tip. In addition, in order to meet different welding requirements, there will be different specifications of soldering iron tips, and the common ones are cone-shaped, chisel-shaped, circular bevel-shaped, etc.
2. Internal heating type electric soldering iron
What types of common electric soldering irons are there?
The internal heating type electric soldering iron is composed of a handle, a connecting rod, a spring clip, a soldering iron core, and a soldering iron tip. It is named because the soldering iron core is installed inside the soldering iron tip.
The internal heating type electric soldering iron heats up quickly, has a high heat utilization rate (generally up to 350-C), saves power consumption, and is small in size, and has been more widely used, as shown in the figure below.
3. Constant temperature electric soldering iron
What types of common electric soldering irons are there?
The soldering iron head of the constant temperature electric soldering iron is generally equipped with an electromagnet temperature controller, and the temperature control is realized by controlling the power-on time. When the circuit is energized, the temperature of the electric soldering iron rises. When the predetermined temperature is reached, the strong magnetic sensor reaches the Curie point and the magnetism disappears. In this way, the power supply is stopped when the magnetic core is disconnected. When the temperature is lower than the Curie point of the strong magnet sensor, the magnet returns to magnetism and attracts the permanent magnet, the control switch is turned on, and the temperature of the electric soldering iron continues to rise. Reciprocating in this way, a constant temperature electric soldering iron with a basically constant temperature is obtained, as shown in the figure below.
4. Soldering iron
What types of common electric soldering irons are there?
Tin-absorbing electric soldering iron is a desoldering tool that integrates piston-type tin absorber and electric soldering iron. It has the advantages of convenient use, flexibility, and wide application range. The disadvantage is that only one solder spot can be desoldered at a time.
