What are the different types of electric soldering iron
1. External heating electric soldering iron
Soldering iron tip, soldering iron core, shell, wooden handle, power lead, plug, and other components make up this tool. This sort of electric soldering iron is known as an external heating type because the soldering iron head is housed inside the soldering iron core. The most important part of the electric soldering iron is the core. It is created by parallel winding the heating wire on a hollow porcelain tube. Two wires are extended out to connect with the 220V AC power source, and the mica sheet in the center is insulated. External heating electric soldering irons come in a variety of specifications, but the most popular ones are 25W, 45W, 75W, and 100W. The soldering iron tip heats up more quickly the more power it has.
2. Internal heating type electric soldering iron
It consists of handle, connecting rod, spring clip, soldering iron core and 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 common 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 When the soldering iron tip needs to be replaced, the spring clip must be withdrawn first, and the front end of the soldering iron tip should be clamped with pliers.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.
3. Constant temperature electric soldering iron
The temperature of the soldering iron increases when the electric soldering iron is turned on because it has a temperature controller with a magnet in the constant temperature electric iron head to control the power-on time to achieve temperature control.The magnetic core contact is disconnected when the Curie point of the strong magnet sensor is reached, which also ends the power supply to the electric soldering iron. When the temperature drops below the Curie point of the strong magnet sensor, the strong magnet reverts to magnetism and draws the moving magnet. The control switch's contacts are closed by the permanent magnet in the core switch, which also keeps the soldering iron's power supply going. The goal of temperature control is accomplished by repeating this cycle.
4. Tin-absorbing electric soldering iron
It is a desoldering instrument that combines an electric soldering iron and a piston-style tin suction device into one. Its features include ease of use, adaptability, and a broad range of applications. This soldering iron's drawback is that it can only desolder one solder joint at once.
