It’s not pretty, and could come loose. Solder is conductive, so the current will transfer correctly. It’s not advised to have solder connections like that because they are fragile. So you can keep
It if it’s the best you can do:)

Hello nomad, maybe resoldering it is a good idea. One HUGE tip I can give you is to presolder wire by warming it up and rubbing the solder onto the wire, this will make is easier when you go to solder it to a board or another wire.

That's good advice, josh. The process is called Tinning. Meaning, you add a bit of solder to the tip first, then hold it against the wire to heat up the wire. Then add the solder to the wire once it's heated up to absorb in.

Also, for the strongest solder joint, remember that you don't melt the solder with the iron. Rather, you want the wire to melt the solder.

there's always the NASA soldering technique, a bit much in my opinion.

hi vertigo

i have a metal with magnefying glas and light too.
the flux is a good tip.

I really like the looks of that 3d printed wire holder. I've always struggled with getting the wires to hold steady in the proper position. I've tried many tools to assist.

Liquid flux really makes the difference. It cleans the wire when heated and the solder flows nicely and is sucked into the joint. Probably any brand would do but this is the stuff I use. I really like it:

I have a similar set of metal alligator clamps, but I find they are flimsy, will move and will move the wire when they clamp them. I almost always use my 3d printed helper instead when soldering wires, as the large grippers make it dead easy to align them. Admittedly though, your metal helper clamp thingies do look better designed than mine with a straight rod so you can move them in/out without changing the orientation. Mine looks like this

whenever I need to move the clamps closer, it twists the wires.

Anyway, whatever does the job:)
