How to Solder Copper Wire to Copper Wire

Soldering is a skill that every DIY enthusiast should have in their toolbox. A soldering iron can help you join and repair metal pieces, like copper wire. Here’s an essential guide to soldering copper wire using a soldering iron. You’ll be a pro in no time!

Gather Your Supplies

Before you begin, make sure you have all the necessary supplies. You’ll need a soldering iron, flux-cored solder, copper wires to solder together, and anti-static tweezers. If you plan on working with electrical components, also make sure you’re wearing insulated gloves and safety glasses for protection.

Prepare the Wires for Soldering

Start by stripping off about 1/4 inch of insulation from the ends of both wires. It helps to use pliers or wire strippers so that the insulation is removed cleanly without damaging the wires themselves. Once both wires are prepped, twist them together until they form one solid wire piece. Then use your tweezers to hold them firmly in place while you solder them together.

Heat Up Your Iron  Set your soldering iron to its medium heat setting—around 350F–400F should do it—and apply it directly onto your joint where the two wires meet for about 10–15 seconds or until it reaches melting point. Once melted, feed some flux-cored solder into the joint and allow it to flow around the connection before removing your iron from the joint area. The solder will harden within a few seconds of cooling down, and voila! You have successfully soldered two copper wires together!


Soldering copper wire may seem intimidating at first, but with practice, it can become second nature in no time! With this simple guide, we hope we’ve given you confidence in tackling your next project requiring soldering skills! Always remember to take safety precautions when handling any sort of electrical work and, if necessary, seek professional help if needed. Good luck and happy soldering!
