Seven factors that cause the tip of the soldering iron not to stick to the tin when welding the solder wire
1. Consider the quality of the soldering iron itself.
2. If the temperature is too high, it is easy to cause severe oxidation on the tin surface of the soldering iron tip.
3. Do not eat tinned surface before use.
4. Using incorrect or defective cleaning methods.
5. The use of impure solder or flux interruption in the wire.
6. "Dry burning" soldering iron tip, such as: the soldering station is not in use, and there is no tin on the surface of the soldering iron tip, which will cause rapid oxidation of the soldering iron tip.
7. Exposure to organic matter such as plastics, lubricating oil or other compounds.
In order to better solve this situation, we can use a knife to scrape off the oxide layer of the soldering iron tip to expose the copper that has not been oxidized by air. Then, put it in the rosin box and dip it, then dip it in tin, and it can be used normally. However, this method is not completely removed. At the same time, if it is scraped off for a long time, the tip of the soldering iron will become thinner and affect heat transfer, resulting in a drop in temperature and even damage to the tip of the soldering iron.

Also, immerse the oxidized soldering iron tip in a container filled with alcohol, take it out after 1 to 2 minutes, the oxide will be completely and cleanly removed, and the soldering iron tip will look brand new. It has no corrosive effect on the tip of the electric soldering iron.
