Let's review whether the soldering iron tip is used to iron hot melts such as plastics, glues, films, etc., so that the tin originally hanging on the soldering iron tip slips off, thus causing the soldering iron tip to be oxidized. If there is no tin, we will energize the soldering iron head for a period of time to melt the hot melt with a higher temperature, and then remove the hot melt on the soldering iron head with a wet sponge.
