How To Solder Two Small Wires Together

Let the solder melt and flow over the wires.

How to solder two small wires together. There are multiple techniques for splicing wires without solder that result in a tight wrap including some that overlap the wires before twisting to give a larger overall spliced area. 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. Another approach that sometimes works is to first use a few turns of much finer wire to hold the two main wires together the whole blob then being soldered.

This process should melt the solder and coat both wires evenly. Secure both sides of the rejoined wire so they wont move when touched with the iron. Tin the wire.

The majority of solder comes in the form of a coiled length of wire or less commonly as pellets with a range of diameters or gauges available to suit various applications and joints. Use a thin solid wire 28 AWG-30 AWG and wrap it around both wires. Place soldering iron under the wire.

Definitely wear safety glasses because hot solder can pop. Use rosin core solder. When done properly you have a strong conductive connection that turns two separate wires into one.

They should be propped up off the workspace so you can have access to the area under the wires. Make seven or eight turns and cut the excess of the wire. All of these approaches require that the wire material be solder-able with any enamel or oxide coating scrubbed off.

Touch the tip of the soldering iron to the copper wires. Then add some solder until the wire is soaked with solder. Heat the pads and melt a small amount of solder on to each pad and let it cool.
