 How to Solder Wires Together (Best tips and tricks)

Learn How to Solder Correctly. In this video I show you the tools, tips, tricks, and techniques to properly solder, from what type of solder and flux you should use to how to splice the wires together for a strong soldered joint. I show you how to strip the wires, add heat shrink, splice the wires, solder, and melt the heat shrink to make a perfect soldered connection!

When splicing wires together, it is important to get an electrical connection that will keep conducting even after your soldering iron has cooled off. Paramount to this is getting a good mechanical connection between the wires, not just an electrical one.

Freshly stripped multi-filament wires need some attention before they will take well to being soldered.

First, the filaments of each wire should be twisted together, or pigtailed, to keep them orderly and behave more like a single entity.

I prefer to add some soldering resin to the filaments at this point too. It really helps the solder flow when tinning the wires. If using flux core solder, this step is not critical, but it still does help.

Tinning the wires (melting some solder into the filaments with your soldering iron) before joining them will make the next step of soldering of the splice much easier. It helps distribute the heat quickly, and the pieces require heat for a much shorter time, since you don't have to spread as much solder around later. This reduces the possibility that you'll melt through the wire shielding near the splice, or damage nearby components if soldering to a circuit board or to a component itself.

You want even distribution of the solder between the filaments, but not so much that the solder starts to swallow the filaments. The top wire in the picture is just about right, but the bottom one has too much solder. Too much solder will make the wires quite stiff, and they still need to be fairly pliable for the next step.

In order to resist being pulled apart, the wires should be wrapped around each other before the soldering takes place. This will make it so that if the wires are pulled on it is not the solder holding things together. Solder's primary function is conducting electricity, not gluing things together (though it certainly does help with that too).

Wrap one wire around the other, taking care to leave enough metal exposed above the sheath so the other wire can be wrapped around it in turn. The turns of the wrap should sit next to each other and not overlap. Keep your wraps tidy.

Unfortunately my second wrap got rather untidy. Hopefully you can learn from having a bad example to criticize.

Now that the two tinned wires are wrapped around each other, we can re-apply the soldering iron and the solder from each wire will melt and mingle, forming a nice solid solder joint. It will be necessary to add a little more solder to really fill in the cracks and get a high strength, low resistance joint.
