How To Solder Two Electrical Wires Together

When soldering wires with a big diameter it is not easy to bend or twist them.

How to solder two electrical wires together. This will heat the wire to allow your solder to melt. There are three main ways to solder wires together. The wires will melt and will get soldered together.

You need to wrap the wires one around the other. 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. Do it in such a way that the wraps do not overlay.

I will show you how to solder wires together the right way to seal the solder joint with heat shrink is a must and you also need to make sure you do not have a cold solder joint. For large gauge wires 14awg for an antenna perhaps make a Western Union splice then solder it. The only way to safely join two flexible mains leads is with an in-line screw terminal connection box.

Heat the copper and apply solder to the side opposite the heating implement. The wraps should be adjacent and close to each other. By first joining wires together you can solder them in place for a strong connection.

Lay them together overlapping at the soldered part then blob them together. RMA rosin flux is best. Screenshot from YouTube video The wires are then twisted together after which they are folded back against the side of one of the pieces of wire as shown below.

There is one way to twist wires together for soldering- a horizontal twist that yields a continues length of wire. Offer a Variety Of Connectors. An in-line screw terminal connection box for joining mains leads.
