How does an electric soldering iron absorb excess solder on components?

1, other tools: alcohol lamp, tweezers, iron container, sandpaper or grinding wheel, etc. That is, the soldering iron is not plugged in to melt the solder at room temperature and wrap it on the soldering head!

2. Grind welding head with sandpaper/grinding wheel to expose copper!

3. Heat the solder block with an alcohol lamp to melt it, and immerse welding head in it when heating. In fact, you can stop heating and turn off the lights at this time. At this time, the solder will slowly solidify from the surface. At this time, it is easy to hang large pieces of tin by dipping it repeatedly with a welding head, just like fishing with oil bean skin! Ok at this time, let's talk about the use effect!

4, plug in the electric heating for a while, large pieces of tin will melt and drip down! Yes, but this is not the case for daily use. When used in daily life, high temperature for a long time will oxidize this layer of tin. At that time, it was not silvery white, but a dark red. However, this does not affect the use of the welding head. If you roll in a tin block, you will be covered with a layer of tin immediately, and the tin wire will melt quickly.
