How to choose and replace the heating core of electric soldering iron
The heating core of the electric soldering iron is a part of the welding device. The heating core of the electric soldering iron is the core that can make the whole electric soldering iron work. If the soldering iron head does not heat up, the electric soldering iron will lose its function. One type of heating core is metal (stainless steel) with fast heat transfer, and the temperature changes greatly during welding. Ceramic is more resistant to high temperature, and the temperature control is relatively good. It is recommended to weld small parts or stainless steel for long-term welding. The other is Ceramic heating core, you can choose to use ceramics for large parts that have been welded for a long time.
How to Replace the Heating Core of a Soldering Iron
1. First disassemble the soldering iron, and throw away the old electric heating core directly. The wires inside are all burnt out, and the plug part is also burnt out, and the wires have to be replaced.
2. Before installation, it is necessary to cover the connecting wire with a heat-insulating sleeve. If there is no ready-made one, find a section of heat-insulated wire, unplug the sleeve and install it.
3. Connect the pin first, and connect it tightly so that it cannot slide. You can use pliers to pinch it hard. If it slides, it is easy to ignite and burn.
4. After inserting the pin back into the soldering iron seat, wrap the tape on one end of the connector for insulation. This insulation must be done well, and then solder the new wire to the wire end of the soldering iron seat.
5. After finishing everything, just restore the soldering iron. The whole process of changing the core is very simple. As long as the insulation is done well, there will be no problem. For those who often do electronic production, a good electric soldering iron is very important.
The use of electric soldering iron heating core
The advantages of electric soldering iron heating core: simple structure, small size, fast heating speed, uniform heating, fast heat dissipation, safe use without open flame when heating, heating circuit is completely isolated from air, and no oxidation occurs.
There are two main types of soldering iron cores: one is resistance wire winding; the other is resistance paste firing.
Use of soldering iron core: When soldering circuit boards, be sure to control the time. If it is too long, the circuit board will be burnt, or the copper foil will fall off. When removing components from the circuit board, stick the tip of the electric soldering iron on the solder joint, and pull out the component after the tin on the solder joint melts. The temperature of the soldering iron has a certain relationship with the volume, shape and length of the soldering iron tip. When the volume of the soldering iron tip is relatively large, the retention time is longer.
