Soldering irons are essential tools used in electronics and metalwork to join metals together. Applying heat to melt solder, a metal alloy with a low melting point, soldering irons create strong and permanent bonds between metal components. These tools are commonly used in various industries, including electronics manufacturing, jewellery making, and plumbing.The soldering process involves heating the soldering iron to the required temperature, typically between 300 to 400 degrees Celsius. Once the soldering iron reaches the desired heat level, the solder is melted and applied to the joint between the metal components.
