Causes and solutions to the phenomenon of perforation in the soldering iron tip
Perforation of the soldering iron tip is a corrosion phenomenon. The raw material of the soldering iron tip is copper, and the surface is plated with a layer of iron plating for protection. Perforation of the soldering iron tip means that the iron of the soldering iron tip is oxidized under high temperature, and the temperature increases. The higher the temperature, the faster the oxidation rate. Therefore, under the premise of ensuring the welding requirements, low temperature should be used for welding as much as possible! Maintain the soldering iron tip well and develop good soldering tip usage habits. The main reason for the perforation of the soldering tip lies in the main structure of the soldering tip.
1. After being used for a long time, the white light T12 soldering iron tip becomes severely corroded and leaks copper, making it difficult to use. However, the temperature of the original heating core is stable and it heats up quickly. If you add a rejuvenating tip, it will be a new soldering iron tip. As long as you can still generate heat, you can use your new condom! It’s still brand new after resurrection!
Disadvantages: There are also disadvantages. The tin melting speed will be slower at startup, the heating speed will be reduced and the cost will be increased. The temperature recovery speed is better than 936. There are advantages and disadvantages.
2. Use a file to trim off the perforated head and change it to the shape you need.
Disadvantages: It is still possible to deal with large solder joints. Just plate a layer of alloy. Copper oxidizes quickly after being heated and will fall off in a short time. Pure copper is easily oxidized and corroded and has a short lifespan.
3. Add borax to the welding rod. I bought a silver-containing copper welding rod (note that it was a silver-containing copper welding rod), but a major problem was discovered during the welding. The silver-containing electrode will be as silver-white as the original T12 coating after welding. It is estimated that because of the silver content, it is extremely easy to tin and has extremely high hardness. Those who have the conditions can try it. The tip used to weld the hole only needs a little bit to fill the hole.
Disadvantages: Liquid solder can dissolve copper or silver. Once the outer iron plating is damaged and the copper inside is dissolved out, especially when used for welding with current lead-free silver-containing solder, I am afraid it will be corroded again soon. The welding tip is corroded and has holes like cavities. Still use materials that can be dissolved, and the results can be expected.
