Non-soluble soldering iron
Soldering iron is an electronic enthusiasts and practitioners must have a tool, the new soldering iron soldering iron head will have a layer of protective layer, can protect the iron head is not oxidised. This time the soldering iron on the tin is very easy, but some improper operation, continuous heating, the use of acidic flux, do not use without adding solder and other issues will lead to early oxidation of the soldering iron head, can not appear on the tin problem.
Common soldering iron
Some common soldering iron, because it does not have the function of constant temperature and temperature regulation, and because of the low price, not copper or alloy iron head. After power on the soldering iron is in a continuous heating state, the iron head will be easily oxidised, and some soldering irons will even appear the phenomenon of iron head burning red.
Solution:
Need to use a file or sandpaper to polish the soldering iron head, remove the oxidation layer on the surface of the soldering iron head, and then into the rosin, turn back and forth a few times, and add the solder. If this method of treatment, the soldering iron head still can not be normal tin, you need to replace the new soldering iron head, according to the soldering iron model and power, choose the appropriate soldering iron head.
Like some thermostatic temperature-regulating soldering iron, such as the very commonly used 936 model soldering station. Because of its own thermostatic function, constant temperature function, the iron head with alloy iron head, not easy to be oxidised, can be set at a stable temperature work. And this kind of soldering iron not only heats up very fast, some also has a long time without automatic shutdown function, largely reducing the oxidation of the soldering iron head. Therefore, it is recommended to use this kind of soldering iron, which is more convenient.
Note on the use of soldering iron:
When the soldering iron is not in use, it must be timely power-off treatment or add solder to prevent oxidation of the soldering iron head. Do not use acidic flux, it will easily lead to the oxidation of the iron head. You can use rosin and alcohol mixed flux in the welding to assist welding. In the choice of solder, to choose some better solder.
