Two ways to deal with broken electric heating wire of electric soldering iron
What should I do if the heating wire in the soldering iron breaks? A common fault in the soldering iron is that the heating wire breaks. Here are two treatment methods. The simple repair method is to splice the fracture. The quick and reliable method is to remove the heating wire from the barrel. Take it out, first remove the oxide near the break, and then twist it tightly.
A common failure of a soldering iron is that the heating wire breaks.
1. Simple repair method
The broken parts are hinged, but after this connection, sparks often occur due to loose contacts, and after a short time, the contacts break again.
2. Quick repair methods
Take out the heating wire from the barrel, first remove the oxide near the break, and then twist it tightly. After splicing, sprinkle a little mixed powder of glass and electric porcelain around the joint (grind the two at a ratio of 6:1) , after installation, power on for a few minutes, the powder will melt and adhere to the contacts. When repaired this way, there will be no sparks in the contacts and it will be more durable.
How many watts does a pointed soldering iron draw?
1. How many watts does a pointed soldering iron use?
If you are welding small parts, 50W is enough. I usually use the 50W internal heating type, which is more convenient and suitable for novices because it is easier to hang tin on the oblique mouth and the soldering iron head is not easy to burn. After using it a few times, if you feel that the center of the soldering iron head If it's dented or burned, it's better to use a file to repair it.
2. Which one is more suitable for welding small objects?
Have you ever seen computer repairmen? They all use knife-shaped soldering irons (which are not small at all. I initially thought that the sharp tip was only for soldering small parts. Later I learned that this is not the case. It is only under certain circumstances. It may be better). It has little to do with the size of the soldering iron. The key is to practice more skills. Are there any small pieces that are still used in daily use?
3. Do you think the oblique mouth is most suitable for novices?
How many watts can it dissolve quickly without damaging small items? This has nothing to do with the wattage. Just master the welding time. The longest is generally no more than 2-3 seconds. On the contrary, it feels that the wattage is too small, which will lengthen the welding time and make it easier to damage the device.
