Aldeco soldering iron is a hand tool used in soldering, a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint. The soldering iron supplies heat to melt the solder so that it can flow into the joint between two workpieces.For better use heat the parts to be joined rather than the solder directly, allowing the solder to flow into the joint naturally.Proper maintenance, such as regularly cleaning the tip and using the appropriate soldering temperature, can extend the life of a soldering iron and ensure consistent performance.
