Tinning is like giving a haircut to a wire. Just like how you get your hair trimmed to look neat and clean, tinning is a process where we cover a wire with a thin layer of melted metal to make it look shiny and prevent it from getting dirty or oxidized. This metal is usually tin, hence the name 'tinning'. Tinned wires are more durable, resist corrosion and are easier to solder with other wires or components. Think of it like putting a raincoat on a wire to protect it from getting wet and dirty. So, tinning is an important process for making wires strong, reliable and long-lasting.
