Often during soldering, a situation arises when the tin does not stick to the soldering iron. Many begin to blame the instrument for everything, calling it poor quality or spoiled. But not everyone realizes that the soldering iron is not at all to blame.
Most often, the problem occurs due to the selection of the wrong solder, which is only intended for high temperatures. There may also be no tinning of the tip at all, or the person simply does the wrong job.
In no case should the soldering iron be left on for a long time, as it starts to overheat. Because of this, the stranded is oxidized, and the flux rapidly burns out. The sting will quickly become covered with carbon deposits and tin will no longer adhere to it.
Useful tips for beginners
If a person has never soldered, then he should read and remember the following recommendations:
- 1. The tip of the tool must be in rosin. So the sting will not burn out, and the copper will oxidize.
- 2. After finishing work, it is necessary to wipe the sting on any piece of wood. This will remove carbon deposits and traces of flux.
- 3. Under no circumstances should the soldering iron be allowed to overheat. If you are not going to use it for a while, then unplug it.
If you use all these tips, then the likelihood of problems with the soldering iron is extremely small. Is the sting already burnt and does not attract tin well? Don't worry, there is a way out. It is enough to do the correct tinning of the tip again.
Useful tips for the procedure
Tinning is a process by which a thin layer of tin solder is coated on the tip of your soldering iron. It will cover not only the sting itself, but also other parts that you will solder in the future.
The process is as simple and fast as possible. It runs like this:
- 1. First you need to clean the sting from carbon deposits. This can be done using sandpaper or a small file. Cleaning should be done very carefully so that uneven surfaces are not left on the sting. They must be flat and smooth.
- 2. After cleansing, the sting is covered with rosin. If you are using solid rosin, the tip should be heated directly in the rosin, waiting for it to melt. If the rosin is liquid, then it is applied with a brush.
- 3. Once the rosin is completely melted, you need to gently touch the sting to the solder. If you did everything correctly and the soldering iron is well prepared, the tin will start to melt right away. The solder must be rubbed against a hard surface, wood or metal.
If you use these tips, you will avoid many problems and difficulties when soldering.
