How To Solder Car Wires Together

The Easiest Way to Solder Wires Together.

How to solder car wires together. Its the act of using heat via a soldering iron and a fusible metal the solder to create the electrical connection. I will be using a power probe butane soldering gun. A pig-tail where the wires are bent at a 90-degree angle to the rest of the wire is NOT a suitable connection and will cause problems dont do it.

There is one way to twist wires together for soldering- a horizontal twist that yields a continues length of wire. Youll also need some PVC shrink tube. You interweave the threads of the wires together before soldering the joint solid.

The most reliable way of joining two wires together is by soldering. For tools Matt uses his trusty auto-stripper and an affordable soldering iron. For this example we solder the same two 18 AWG wires together end to end.

This tool worked the best for me in the automotive application and make it a breeze get that tuff to reach wires repaired soldered and sealed properly. Once coated sufficiently move the shrink tube and heat it so it makes a snug fit around the wire. Hold them end-to-end with their bare copper ends crossing at a slight angle.

Soldering two wires together requires a soldering iron and solder. When wound tight you should fold the twisted copper piece flat to one wire and cover with insulation tape. Now twist the two copper wires together tightly.

Heres the right way to do it. When your soldering iron is all prepped and ready to go its time to solder the wires. If the wire is stranded twist the strands together with your fingers.
