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!

It's not just a soldering tutorial; it's a lesson in effective, clear, precise and complete communication. Thank you

I got the very best education in soldering from the Navy and I can usually find something snarky to say about almost every YT "how to" video on the topic. Except this one. You hit everything I would have said, and every time I thought of a tip to add (adding silicone, moving heat shrink down from the solder zone, etc.) you mentioned it. Very well done. I'm sending anyone who asks about soldering to this video.

6 years later and this is still the best tutorial ive seen. Not repetitive, goes over common mistakes, and overall helpful. Now i just need you to make a welding one

That was the most informative, direct, sensible, comprehensive, focused, and skilled crash course on soldering I’ve ever seen! He doesn’t waste time, he gets to the point, but also explains WHY you need to follow the steps. Excellent video!

Hi Chris! I hope this comment doesn't get buried.

I have a few tips in addition to what you showed:
- For one, with the lineman's splice it actually helps a lot if you give the wires a pull, the splice will get tight like a knot. Properly done, a lineman's splice that is pulled tight can actually make a good connection without solder, just heatshrink to keep it in place.
- I usually just cut any strands that are sticking out with flush cutters rather than trying to wrap them around as that can be painful sometimes.
- If it's a situation where the wire is experiencing strain--bending, vibration, etc--you want to avoid having too much length of solid solder, because solder is quite brittle. If you did the lineman's splice properly and pulled it tight like I mentioned, you should only need a small blob of solder on either end of the splice.
- Using 63/37 lead solder instead of 60/40 is a bit more foolproof, as with 60/40 you have to make sure the joint stays still as it cools. With 63/37 it's less of a concern
- Silver-bearing leaded solder is mechanically stronger than regular leaded solder, and just as good in pretty much every other respect except cost. If you're not going to need a lot, and the price won't break the bank, silver solder is great for any situation where the solder joint cracking would be very bad.
- I generally recommend people *don't* buy solder from hardware stores, as it's usually only mediocre quality and almost always very thick solder wire. Generally the thinner the solder wire the better. The thicker it is the easier it is to add too much.
- you don't want to heat wires too long or it will start to melt the wire insulation
- you can actually buy heat shrink tubing that shrinks 3:1 instead of 2:1 which can be helpful when you're soldering together wire of two different sizes, or when you can't get an exact size match.

Bro... So thorough. No 2nd guessing, no corny music and no childish punny jokes. Straight forward and educational. Subscribed ✌

[paultrock]

Been soldering (when I need to) for 30 odd years. Still learned stuff from this vid, thanks ChrisFix, you're a legend!

[cindydavis]

This is as thorough and detailed as humanly possible. Thank you

[whykelswhy]

Blown away by how good this tutorial is... Holy crap. Literally the best tutorial I've seen on anything.

[maxbrokeaway]

I've soldered for a living for the last 14 years, and this video is really excellent for people interested in soldering. The information here is quick, thorough, and most importantly - it's accurate. The only extra tip I would recommend is cleaning rosin flux residue off rubbing alcohol using a stiff bristle brush prior to the heat shrink application. Very well done!

[llroman]

His videos are ALWAYS EXCELLANT! Thank you Chris.

[dallingardner]

Hey, building a lightsaber from scratch, and wasn't sure how to solder. So grateful for people like you who share their skills with others. Thanks again!

[LasseHuhtala]

Been soldering for over 30 years, yet I'm here, watching a soldering video. :-)

[SammSheperd]

As someone with extensive soldering experience I approve and appreciate the work put into this

[MrUnicornsinmycereal]

Another chrisfix video ftw! Haven't soldered since highschool and almost 15 years later I needed a refresh to fix my obd1 port for my 95 volvo. God bless chrisfix!

[benclapp]

Honestly one of the best instructional videos I have seen on YouTube. Very organized. Straight to the point. Great camera detail. Thank you

[LostWax]

Aaahhh, it feels so good to watch a YT tutorial that is well filmed, well edited, stresses safety, and made by someone who knows what they are doing. Just found your channel and immediately subbed. Thanks for sharing your knowledge. ❤️

[vincentalykin]

I haven't yet watched through the entire video, but I must say that this is one of the most direct, chronological, detailed, tutorials I have ever watched. You list and link the tools that people would need and explain the differences amongst different tools and materials, adding in information to help further clarify our understanding of the concepts. No fluff, no wasted time. Straight-forward, detailed explanations. This was great.

[gunnutmike]

Thanks for an extremely precise and well shot video . I learned to solder about 50 years ago, but I haven’t done any for at least 20. You covered everything I used to know, plus some things I was never taught. Thanks for making it easier than I remember.

No music.. minimal excess (within reason), clear and concise.. awesome!! Subscribed and thanks!
