Hi everyone,
I have some very fine 34AWG insulated wire. Its core is composed of multiple thin copper strands. I want to splice it to single-strand 22AWG insulated wire. I have tried Scotchloks, but they do not work because they are only rated 19-26AWG.
Does anyone have a solution for this?
Have you tried soldering them together?
No, because I'm afraid the wire would break. I'm prepared to give it a go if there's no better solution.
Solder it and cover the joint with heat shrink tubing.
How do you strip such wire?
You have 34AWG that is made of even smaller strands of what size?
Wirewrap stripper will do the larger 30 AWG.
One option is lightly pull the smaller than 34 thru some 300,320 grit sandpaper.
Fold it half, put the end of wire in the middle, pull it thru a few times.
I've not wire smaller than 30 AWG wirewrap wire myself.

Litz wire is generally self-stripping when soldered.
Hi, I assume you are afraid of the joint breaking due to the finer wire, as suggested solder them together, the fine wire wound around the thicker over as 1cm of length.
Then you must physically stabilize it, use heat shrink then anchor the connection to a flat surface, anchoring the joint itself and either ends about 1cm from the joint.
The middle fixing will kept the joint stable, the end fixings prevent any pulling of the wires.

I was stripping the wire with one of these: Automatic Wire Cutter Stripper Crimping Tool Pliers Electrical Cable Crimper AU | eBay
I agree with the fine grit sandpaper suggestion. I've used that method successfully . It just takes a little finesse.

I'm having trouble visualising this. Could you provide a diagram or image?
The usual amount of confusion - a photo is golden!
I made a comment about Litz wire which is special wire used for "high frequency" coils and very flexible connections.
On further consideration, I presume what you are referring to is stranded flexible wire - multiple strands with an insulating jacket. The strands themselves are not insulated - in fact this is highly undesirable as you wish them to share the current carrying so that current can jump from one to the other if one or two strands break from repeated movement - so that you do not need to remove individual insulation, just the outer jacket. The sandpaper idea is inappropriate - that applies to (single strand) wire insulated by enamel such as is used to wind transformers and other coils.
To remove the insulation from a short section at the end, a tool such as illustrated before is useful; you insert the wire into the blade to the point where you want the insulation to be cut and carefully jam the wire into the slot until the insulation but not the wire itself has been crushed and then pull the insulation away.
Fine stranded wire is best soldered as others have described.

Well only if you can provide a photograph of the actual wire you have.
Hi, I agree with Grumpy_Mike, picture would be invaluable, place a ruler in the picture as well so we can see the size of the wire.

More like clamp a micrometer on the wire but not hard enough to flatten it.
Here is the cable I am working with.
With a little care, some soldering pratice and some heat shrink you will be able to produce a good solid connection that will last. Those wires will solder easily, I recommend getting some liquid flux to aid in your soldering.
Hi, what sort of voltage are you aiming to use this for, its a piece of 3core power flex, a picture of what you want to connect it to will help.
You should be using screw terminal blocks as in the picture attached.
