           Different Uses of Soldering Iron
           Soldering Tools for Circuit Boards
           Used in plumbing such as closing small gaps between two metal pipes
           Craft projects
           Can be used to solder mosaics and stained glass

           For engine and car repair services
           FORMULA:-
           Examples of these four-element compositions are 18/64/14/4 tin-silver-copper-zinc (melting range 217–220 °C)
           and 18/64/16/2 tin-silver-copper-manganese (Sn-Ag-Cu-Mn; melting range of 211–215 °C)
           Types of solder
           Lead-Based Solder. Lead solder, made of lead and tin, is used for most electronic manufacturing applications to
           form a strong bond between the joints of other metals, such as copper and aluminium.

           Lead-Free Solder. Lead-free solder generally has a higher melting point than conventional solder.
