How long does a soldering iron heat up
The power of a 60w soldering iron is very high, but the soldering iron generally needs to be preheated for 3-5 minutes. Although you may see it getting hot and smoking, it may not have reached the melting point of solder. The warm-up time of the soldering iron is also related to the use environment. The warm-up time will be longer in an environment with high wind and low temperature. It is recommended to take some protective measures for the soldering iron (such as adding a sleeve) to ensure that the soldering iron can last. Accumulate heat to reach a certain high temperature.
The new electric soldering iron will have a little smoke and peculiar smell when used for the first time. There is a layer of anti-oxidation paint on the soldering iron, which should be wiped off gently before use. For the first use, the solder should be fully fed to the tip of the soldering iron, so that it can fully absorb the tin and then solder.
