Buy new electric iron, plug in the electricity will be hot, solder a touch on.After a few minutes, however, the solder was stopped at the tip of the iron.Is it the reason why the iron head is oxidized?
Is your hair black iron oxidation of the soldering iron head, iron is hot after you don't use it, then oxidized, iron is in use to avoid this phenomenon, you can use sandpaper to appear inside the copper iron head, and then re tinning, use to often pull the power to use when connected this power, although the trouble spots, but to prevent the oxidation of the soldering iron head burned or help.
The black iron shows that the solder is too large and the iron is too thick at the end of the iron to cause blackening. It is recommended that you use the rosin, solder paste and wet cotton to clean the tip of the iron before you use it next time. This will be helpful for the normal operation of the solder.
Use iron a few minutes after the heat is not easy, because the copper oxide thermal conductivity welding oxidation difference.The solution is to use a fine sand paper or file to re polish the iron head or file a new crop, and then re plating the tin can continue to use. Usually, the steel wire cleaning ball can be arranged in the iron rack box, and the working iron head can be wiped on the cleaning ball for a few times, so that the oxide of the iron head can be removed. In addition, the handle of the electric iron can be held in hand, and the oxidized iron head is dipped in an alcohol container to be heated by 1~ 2min, and the oxide is thoroughly removed. In order to reduce the phenomenon that the soldering iron head does not eat tin, we should try not to electrify the soldering iron without welding. If the iron head impurities, can be a small sponge soaked in water after placed in a small tin, then the iron in the sponge and lightly pull a few, the tip will be bright as new.
