What to do if the soldering iron tip is not soldered
The reason why the electric soldering iron head does not solder is because the surface temperature of the soldering iron head is high and it is prone to oxidation when in contact with air. Once an oxide layer is formed, it is difficult to solder. Therefore, in this situation, we only need to use a blade to gently scrape off the oxide layer, and then use fine sandpaper to polish it. After the clean tin surface is exposed, the electric heating is applied, and then the soldering wire is used to evenly apply the soldering iron head, so that the soldering iron head is wrapped in tin and is not easily oxidized.
Precautions for using electric soldering iron
1, The soldering iron head is prone to oxidation when in contact with air at high temperatures. As long as we always keep the soldering iron head wrapped in tin, it can greatly prevent oxidation and prevent the occurrence of burning.
2, When using an electric soldering iron less frequently, it is best to hang the soldering iron tip with tin, lower the temperature to below 50 degrees Celsius, and then adjust the temperature to the appropriate temperature for the next use. This can prevent long-term dry burning and oxidation of the soldering iron tip, and also extend the service life of the heating element.
3, Try to avoid using an electric soldering iron to heat things other than the soldering wire, such as plastic, because once the soldering iron tip sticks to other materials, it will definitely cause the solder to not stick to the tip.
4, An electric soldering iron is just a heating tool, and we should try to avoid using a soldering iron head to pry the pins of the components, as this can easily cause trauma to the soldering iron head. Once the soldering iron head is deformed, we need to use a file or sandpaper to polish it flat before use.
In general, the maintenance of an electric soldering iron is actually aimed at the soldering iron head. As long as we pay attention to avoiding dry burning of the soldering iron head in our daily lives, as long as we ensure that there is always tin wrapping on the soldering iron head, there will be no situation where it cannot be soldered.
