The flux is much more stable in high heat and high temperatures than most organic fluxes. This results in minimal smoke, order, and easy-to-remove residue.
The built-in flux core helps the ultra-thin solders flow easily into the joint. The tin & lead wire is easily and quickly soldered due to the smooth flow. This creates a strong soldering point. Soldering wire is easier to use than the lead-free alternatives and is great for beginners and inexperienced soldiers.
A soldering wire can be used in a wide array of jobs and applications. It can be used to easily fix complicated circuit boards or simple household electronics.
