What is wire glue and how does it work?
Wire glue, also known as wire tinning or wire soldering flux, is a type of adhesive used to join two or more wires together. It works by creating a strong bond between the wires, allowing them to conduct electricity efficiently. The glue is typically made from a combination of chemicals that melt and flow when heated, forming a strong and durable connection.
The process of using wire glue involves applying a small amount of the adhesive to the wires, then heating it with a soldering iron or other heat source. As the glue melts, it flows into the gaps between the wires, creating a strong and secure bond. Once the glue has cooled and hardened, the wires are securely joined together, allowing them to carry electrical signals with minimal resistance.
