I bought an electric iron, 50W, in the dark when you can see the iron head burned red, but it does not touch tin, this is how ah, the way to spend money, even if I am poor ah!
It's simple. First remove the oxide layer with a file, heating electric soldering iron with rosin, then it can be used as normal.After use should pay attention to control the temperature, as long as you can melt solder. You can use the plug or a switch to control the temperature so as to avoid the iron head oxidation.
1, select the temperature is too high, the iron head surface attached to the tin quickly dissolved volatilization, resulting in severe oxidation. High temperature is required Duojiaxi2 、 use incorrect or defective cleaning methods. Clean sponge and iron head cleaner are recommended.3 、 use impure solder or solder flux in the welding wire to be interrupted. Guarantee the quality of tin4, the work temperature exceeds 350 degrees, and stop welding more than 1 hours, soldering iron on the tin is too little. Tin protection is recommended when not in use5, "dry" soldering iron head, such as: welding table open, no use, and the iron head surface without Tin, will cause the iron head rapid oxidation.6, the use of flux is highly corrosive, resulting in rapid oxidation of the iron head; selected flux.7. The use of neutral active flux is recommended8 、 do not often clean the oxide on the head of the soldering iron. Wash the iron head more
The tip of the soldering iron is mostly made of copper. Copper reacts with oxygen in the air at high temperature to produce black copper oxide (CuO), while copper oxide does not adhere to tin.Processing method of iron head "burn": iron electric heating to the normal temperature, and then use the file or sand the black copper oxide on the surface of the iron head worn, immediately after dipped in rosin, then you can hang on the tin.
