How to use the soldering iron tip so that it will not be oxidized
The soldering iron has been used for too long. A soldering iron that has been left for too long or has been used by someone who is not very good at using it will oxidize, ranging from not being hot enough to being unable to even tin. If you do not know the situation and use it forcefully, the heating wire inside will be scrapped. , the heat cannot be dissipated. So, how to deal with the oxidation of the soldering iron tip, and how to use the soldering iron tip so that it will not be easily oxidized?
So, what to do with the soldering iron tip? This needs to be handled more carefully, but it's not too complicated.
First, cut off the power immediately. Wait until it is cool and no longer hot, use a file or sandpaper to carefully polish the soldering iron tip - pay attention to feel out a certain tip, or polish it to the original shape. It is best to use sandpaper because it is relatively smooth, or for the severely damaged soldering iron head, use a file to smooth it first, and then use sandpaper to smooth it in the final stage. Then, turn on the power. At this time, it is best to find some cotton soaked in alcohol (industrial alcohol or disinfectant alcohol can also be used, beer, I have tried it, it should be OK.) If you can't find it, you can also use water, but remember, Be sure not to get the cotton too wet or it may cause splatters.
The purpose of preparing this wet cotton ball is as follows:
When the newly ground electric soldering iron is powered on and heated, it is not hot enough to tin, but it is easy to oxidize. At this time, if you can wipe it with a wet cotton ball, it can effectively prevent oxidation - of course, it is best to use Alcohol on cotton. When the soldering iron tip is hot enough, you can first dip it in some rosin - a little is enough, just a little water (the same is true when using an electric soldering iron. Every time you solder something, dip it in rosin first, and then apply tin or Welding will help melt the tin and improve its fluidity, and the quality of welding will be greatly improved.)
Then, carefully apply a layer of tin evenly on the soldering iron tip. If you do it well, you can see that the tin is obediently spread evenly on the soldering iron tip in a thin layer. If you turn the soldering iron, you can also see The tin liquid is flowing - if you see this effect, it means you have done a good job. However, the best thing is to be patient, turn off the power, wait for it to cool, then turn on the power again, and then apply a layer of tin , repeat this two or three times, the soldering tip will be better protected. Of course, if you are in a hurry to use it, just use it directly.
In the process of using the electric soldering iron, including the completion of one welding, you must always put a layer of tin on the soldering iron tip before cutting off the power. In short, we must always keep it protected by a layer of tin to avoid oxidation. At the same time, Convenient for welding. The skills of using an electric soldering iron cannot be learned once or twice, so you must do more hands-on work and pay attention to continuously improving your soldering skills. Slowly, you will feel that the soldering iron in your hand is becoming more and more obedient. Even other people's soldering irons are easy to use - because soldering irons are often not something we can choose, so you have to master the characteristics of rosin and tin. , use it and you can play with it.
