The soldering iron is a soldering tool that we often use, but sometimes we find that the soldering iron is black and does not stick to the tin, which brings great inconvenience to our work. So, how to solve this problem?Below, I will introduce two simple methods to help you easily solve the problem of black soldering iron without tin.
Method 1: Use acid flux.
Acid flux is a chemical agent specially used in soldering irons, which has strong oxidizing properties and is able to remove the oxide layer from the surface of the soldering iron, so that it can regain its ability to get tin. The method of using acid flux is simple, just soak the soldering iron in acid flux and rinse it with water.
However, it should be noted that acid fluxes are somewhat corrosive, so you should pay attention to safety when using them. In addition, if the problem of blackening and non-tin of the soldering iron cannot be solved after using acid flux, it is recommended to use method 2.
Method 2: Use flux.
Flux is a chemical agent specially used for soldering, which can remove the oxide layer on the surface of the soldering iron and improve the soldering iron's tin holding ability. The method of using flux is also very simple, you only need to apply the soldering iron an appropriate amount of flux, and then heat the soldering iron to melt it.
It should be noted that flux has a certain corrosiveness, so it is necessary to pay attention to safety when using it. In addition, if the problem of black and non-sticky soldering iron cannot be solved after using flux, it is recommended to replace the soldering iron or send it to a professional maintenance personnel for repair.
The above are the two ways to solve the problem of black and non-stick soldering iron, I hope it can help you. When using these methods, it is important to pay attention to safety issues and avoid unexpected situations.
