How to solve the problem of soldering iron tip overheating without soldering

Release Date:2016-08-16
If the soldering iron tip does not solder after being heated to high temperatures, the following method can be used to solve it:
Firstly, clean the area around the soldering iron tip with fine gauze until it shines brightly.
Secondly, prepare rosin and tin, crush the rosin and some tin into powder, and place it on a clean copper or iron plate;
Thirdly, heat the soldering iron with electricity, and before it reaches its maximum temperature, use a soldering iron tip to rub against the broken pieces of rosin and tin. This way, the soldering iron tip will be coated with a layer of tin
Fourthly, disconnect the power supply and wait for the soldering iron tip to cool down. You can solder it on the next use;
Note:
The above methods are applicable when the soldering iron tip is oxidized. If the heating ability of the soldering iron core of the soldering iron tip decreases, it is necessary to replace the soldering iron core in a timely manner.
If the first method has no effect after trying, you can try using the second method.
