No crimp heat-shrink terminals with solder just about mandates use of a electric heat shrink gun. They're inexpensive at Harbor Freight.

The above terminals do not use regular 60/40 electronics solder. A third metal card Bismuth is added and it reduces needed to melt temperature by some forty degrees.

I just purchased a box of no crimp heat shrink butts for 26-24 wire. The insulator is transparent clear.

I hope this helps someone and at least, is entertaining.

Be carefull with thoes, a couple other groups I am in for other hobbies jumped on that bandwagon. they are natroious for producing cold solder joints and cracking.

look back a couple posts, I made a video using them. They work fine if you take your time.

I never said it was the product its self, just to watch when you use them. I have used them and yes they are a very conveniant thing. Just saying for guys that are using hundreds of them conecting led lights and such thery are seeing failure rates up to 10%. now is this all the fault of the conectors, probably not. when your doing 300 in one day maybe your not being as carefull as you could. I just ordered 1000 of them for 18ga wire for my next project ;)

IDK if they worth it for that kind of project. I can actually go faster with normal shrink and regular solder. I can see how you can get a cold joint, if not using a heatgun, vs a lighter etc.

no aparenty they are using heat guns, I think people like them as the tube is the glue type that forms a water proof joint when done. conveniance...

Who would think butt splicing 12ga to 10 ga would have so many answers.

Well, besides all the replies to OP's original post, there's also those who comment on the commenters. ;)

I think many read the OP’s post then they reply without reading any of the other posts.

Because opinions are like, well ya know as everyone has one!!!

So true and folks feel that even though 1 or more solutions have been stated 5 times or more, they just have to duplicate what has been said adding their 2 cents.

Here are some soldering tips...

I use a scalpel sharp utility blade knife to scrape mild oxidation off stripped copper strands. I lay small wire atop a finger the scrape the blade sideways perpendicular to the wire strands. I avoid the blade thing if I had the hiccups.

Cold solder mistakes are created by oxidized copper and using hardware store solder. Terminals actually see a "Blush" race across it when the tin or copper gets hot enough.

Hardware store plumbing PASTE not liquid flux can be used. But not frequently. It simply eats the solder gun 10x faster than rosin. But it does strip off nasty corrosion. For an emergency repair to old wire oxidized to dark purple, I've scraped the exposed strands shiny with a blade then used hardware store paste flux. Don't expect the wire to last forever.

I cannot think of a better way to learn to solder than to get ahold of some electronic 60/40 solder, and small tin of hardware store paste flux and complete trial soldering jobs on a bench. It happens fast you can see each soldered strand of wire. The solder flows like water and doing this is 10 times easier than you think when you have the right stuff.
