Thanks all for the responses to my original question on the above named
subject. Looks like a trip to the local depot is in order for some
new wire.

Anyway, I saw several responses talking about "properly soldered"
splices. Which, for me, begs the question what is a properly soldered
joint and how do you do it? Once again, thanks for all the input.

Try googling "how to solder". Lots of good stuff.

Actually pretty easy.

Slide on 3 or 4 inches of shrink wrap. Then just overlap each wire end 2
inches or so and wind the end of each wire around the opposing wire.
Heat the joint with your soldering iron and melt in a bit of solder (not
too much or it just makes a big lump). The slide the shrink wrap over
the finished splice and heat it until it shrinks around the splice. You
can also just wrap it with electrical tape instead of shrink wrap, but
it doesn't look as good and may start to unwind in a couple of years.

When I splice "zip-cord", I cut the two wires offset from each other
about 1.5 or 2 inches. Then I slip heat shrink tubing over the longer
wire and strip the insulation ~1/2 inch. Then I just overlap the bare
wire ends and solder them together, shrinking the tubing over the
joints to insulate them. If I were splicing wire for mains power,
I would put another heat shrink tubing over both of the joints for
extra protection.

If you are asking specifically about how to solder, there are several
tutorials online, likely illustrated even.

Usually, I simply twist the two ends together and bend them back over inline
with the conductor, but if I have smaller than optimum shrink wrap
available, that makes a lump which is hard to slide over. In those cases, I
twist each loose end separately--in line--over the other...sort of a
modified 'linemans splice.'

I do this in almost all cases, unless I don't have the proper size shrink in
the drawer.

OTOH, for the OP's purposes, there are any number of solderless solutions
available. Wire nuts work well, even if they're ugly...use the proper size.
Tape or shrink them for security...also covers up the ugly garish colors.
Crimp type butt connectors require almost as much care (and equipment) as
making a solder joint, and I don't recommend them, but they work if you have
the proper crimper and know how to prepare the conductors and use the
crimper. Tape or shrink without solder can do the job, too; but mechanical
strength, moisture resistance is an issue.

I do the same two things. The twist is important, since the solder is NOT
supposed to provide the mechanical strength of the connection...it is there
to secure the electrical connection. Or so I've been told.

I would agree completely if we were splicing solid wire. But my experience
is that by mashing the strands together and soldering, the joint is actually
stronger than the original wire. My theory is because of the enormous
surface area of all those strands (x2) for the solder to bond with.

Not sure I'd say stronger than the wire itself, (I used to have access to a
tool to test this) but otherwise that logic makes sense to me. I've done a
few splices that way...push the ends of stranded into each other, squeeze
them closed, solder, squeeze it smooth, and wrap it.

It's one where the solder wets and adheres to the metal, as opposed to just
sticking to its surface.

If the solder looks like a water drop on a waxed car -- with very sharp
boundaries as if the metal were repelling it -- then either it wasn't heated
adequately or the copper wire wasn't clean. The solder should flow freely
onto the metal and start to become alloyed with it.
