How to prevent blackening of soldering iron tips
The soldering iron tip is a good tool for our welding equipment. The application of the soldering iron tip plays a very important role in the welding equipment, especially the improvement of welding is very important, but we often find that the soldering iron tip sometimes turns black after working situation, why?
First of all, the black hair of the soldering iron is mainly reflected in:
1. Generally, the surface of the iron tip is oxidized and blackened after being heated. Due to long-term exposure to the air, the soldering iron tip is oxidized. Therefore, the circuit board and wires should be cleaned before welding, and the oil, paint and other dirt should be cleaned.
2. When dealing with the soldering iron tip, it is also necessary to use alcohol when necessary. After cleaning, use an electric soldering iron to heat the soldering point and apply rosin or solder paste. This is an effective measure to protect the soldering iron tip from oxidation, and use an electric soldering iron to seal the soldering point Tin separately (that is, let the soldering point be tinned first).
3. In order to prevent blackening, we should also use electric soldering tin to connect two or more soldering points together, which is effective for the defense of the soldering iron tip.
4. If necessary, you can use the electric soldering iron tip to directly touch the solder wire when the tin is melted, and the solder wire will melt when the temperature of the electric soldering iron reaches the melting temperature, so as to reduce the oxidation effect on the soldering iron tip.
5. If the soldering metal is too large and the soldering iron cannot heat the metal to be soldered to the melting temperature of the solder, the power wattage of the soldering iron should be increased.
