How to solder so that the soldering iron's tip doesn't rust
The soldering iron took too long. Soldering irons that have been left for too long or used by people who are not very good at using them will oxidize, ranging from not being hot enough to tinning. , the heat cannot dissipate. So, how to deal with the oxidation of the soldering iron tip, how to use the soldering iron tip so that it will not be easily oxidized?
So, what to do with the tip of the soldering iron? This one needs to be handled with care, but it's not too complicated.
First turn off the power immediately. When it is cool and not hot, use a file or sandpaper to carefully polish the tip of the soldering iron - pay attention to touch out a certain point, or polish it with the original shape. It is best to use sandpaper, because it is relatively flat, or for a severely damaged soldering iron tip, 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 dipped in alcohol (industrial alcohol or disinfectant alcohol, beer, I tried it, it should be okay.) If you can’t find it, you can also use water, but remember, Be sure not to get the cotton too wet, or you may cause splatter.
Preparing this wet cotton mass works as follows:
The freshly polished electric soldering iron is powered on. When it is heated, it is not hot enough to be tinned, 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 a soldering iron. Alcohol damp cotton. When the tip of the soldering iron is hot enough, you can dip some rosin first - a little is enough, just a little bit of water (the same is true in the process of using the electric soldering iron, every time you solder something, first dip the rosin, then tin or Welding will help the melting of tin and improve its fluidity, and the quality of welding will be greatly improved.)
Then, carefully coat the tip of the soldering iron evenly with a layer of tin. If it is done well, you can see the tin obediently spreading a thin layer evenly on the tip of the soldering iron. If you turn the soldering iron, you can also see Until the tin liquid is flowing - if you see this effect, it means that you have done a good job, but the best thing is to be patient, turn it off, wait for it to cool, turn it on again, and then apply a layer of tin , Repeat this two or three times, the tip of the soldering iron will be better protected. Of course, if you are in a hurry to use it, just use it directly.
In the process of using an electric soldering iron, including the completion of one soldering, you must always put a layer of tin on the tip of the soldering iron before turning off the power. In short, we must always let it be protected by a layer of tin to avoid oxidation. Easy to solder. The skill of using an electric soldering iron cannot be learned once or twice, so you must do more and pay attention to continuously improve your soldering skills. Slowly, you will feel that the electric soldering iron in your hand is becoming more and more obedient, even other people's electric soldering irons are also easy to use - because electric soldering irons are often not our choice, so you have to master the characteristics of rosin and tin , to use it, you can play it.
