How to choose the right heating core for an electric soldering iron and how to replace it
The heating core of the electric soldering iron is a component of the welding device. The heating core of the soldering iron is the core that makes the entire soldering iron work. If the soldering iron head does not heat up, the soldering iron will lose its function. One kind of heating core is made of metal (stainless steel) which has fast heat transfer and the temperature changes greatly during welding. The ceramic one is more resistant to high temperatures and has relatively good temperature control. It is recommended to use stainless steel for welding small parts or those that do not need to be welded for a long time. The other is Ceramic heating core. For large parts that need to be welded for a long time, you can choose ceramic ones.
Selection of electric soldering iron heating core
1. Before purchasing a reliable heating core, we must first confirm the qualifications of the company. Is it a well-known company in the country and what are its qualifications? How is the user reputation?
2. Why can this company provide users with a high-performance and high-quality heating core? This requires confirming the company's resources, whether it has strong technical support, and can generally operate stably for more than ten years.
3. Product performance, stable performance, companies with a customer renewal rate of more than 95%, the product performance will definitely not be bad!
4. The price of the product should be transparent, and there should be no arbitrary charges. The good ones may be too expensive, and the cheap ones may not be good. Therefore, we must weigh the cost-effectiveness of the product. The same configuration and the same performance, basically the price plays a decisive role.
5. After-sales service, whether the after-sales service can provide 7*24-hour customer service + technical service, users will feel at ease only if the service is in place in a timely manner. to
How to replace the heating element of a soldering iron
1. First disassemble the soldering iron and throw away the old heating core. The wires inside are all burned out, and the plug part is also burned out. All the wires must be replaced.
2. Before installation, you need to cover the connecting wire with a heat-insulating casing. If there is no ready-made one, find a section of insulated wire, unplug the casing and install it.
3. Connect the pins first, and make sure they are firmly connected and cannot slide. You can use pliers to pinch them hard. If they slide, they will easily spark and burn.
4. Insert the pins back into the soldering iron seat and wrap one end of the connector with tape to insulate. This insulation must be good, and then weld the new wire to the wire end of the soldering iron seat.
5. After everything is done, just restore the soldering iron. The whole core replacement process is very simple. As long as the insulation is properly handled, there will be no problem. A good soldering iron is very important for people who often make electronics.
How to use the soldering iron heating core
The advantages of the electric soldering iron heating core: simple structure, small size, fast heating speed, uniform heating, fast heat dissipation, safe use without open flame when heating, the heating circuit is completely isolated from the air, and no oxidation occurs.
Classification of soldering iron cores: Currently, there are two main types of soldering iron cores: one is wound by resistance wire; the other is fired by resistance slurry.
Precautions for using the soldering iron core: When soldering circuit boards, be sure to control the time. If it is too long, the circuit board will be burned or the copper foil will fall off. When removing components from the circuit board, you can stick the soldering iron tip 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, length, etc. of the soldering iron tip. When the volume of the soldering iron tip is relatively large, the holding time will be longer.
