Why doesn't the soldering iron stick to the solder?
1, the soldering iron use time is very long, the internal heating core aging or damage, the heat issued by the melting point of the solder can not reach the solder, resulting in the soldering iron head does not stick to the solder.
2, the daily use of the process, after the use of the soldering iron does not have the soldering iron head for tin treatment, resulting in the soldering iron head at high temperature and air oxidation.
3, after using the soldering iron, did not do in time to cut off its power supply. The soldering iron is in a high temperature state for a long time, and air oxidation, resulting in non-stick solder.
4, daily welding in pursuit of convenience, the use of acidic flux, flux in the high temperature state makes the soldering iron head oxidation.
5, the iron head itself, the use of some of the material is not good iron head, such as some iron head directly iron, this kind of iron head itself is very easy to oxidation.
How to solve the soldering iron head does not stick solder
1, prepare high quality solder, rosin, high temperature sponge. Put the soldering iron on the power supply, wait for its temperature is high, the soldering iron head into the rosin, back and forth for shaking. Then take out the ready solder, contact the soldering iron head can melt.
2, if the iron head has oxidised black, you can prepare a file (no file, if you prepare sandpaper is also available) with a file or sandpaper on the iron head for grinding, the iron head surface of the black oxide layer can be sanded off.
3, the soldering iron is generally made of copper metal, oxidation of the surface will form a black copper oxide (CuO) copper oxide is not sticky solder, can be inserted into the soldering iron head content of 90% alcohol solution to deal with. It should be noted that the unheated state should be put into, and then electrified, 1-2 minutes after the removal, you can solve the problem of oxidation of non-stick solder.
