What Does Tinning Wire Mean?

Tinning is a process of using a soldering iron to melt solder around a stranded electrical wire. Tinning the tips of stranded wires holds the fine wires together and makes it easy to connect them to screw terminals or other connectors.

What is the purpose of tinning a wire?

The main point of tinning stranded wires is to create a stronger contact point when connecting wires to the correct terminals. When you use a soldering iron to add rosin-core solder to the wire strands, the solder fills in the voids between the wire strands and causes the loose, fine wires to become one solid wire.

What is tinning and why is it important?

Tinning the tip means covering the tip with a layer of solder. ... Tinning the tip extends the life of the tip by preventing oxidation and corrosion, but it also causes the solder wire to melt and flow more easily over the parts you are joining, making the overall soldering process go smoothly.
