Where can I buy some small wire ( about # 28 to 30 ) that has the
enamel type of insulation that can be soldered and the heat will melt
the insulation ? There was some on ebay I bought that did not seem
to work. After checking it out, it seems that it needs to be heated
to almost 400 deg C and when I tried that, it did not do all that
well.


Wire such as Essex Soderon is solderable, as you want. The
insulation melts
at approx. 237°C, well below 400°C.
Amazon, for one, has it at

Funny story...
25 years ago, I contracted some LCD monitors from Japan as part of
a product offering. They had been modded using that type of wire.
The QC manager took one look and insisted that they all be rejected.
YMMV



As far as those mod wires often used on circuit boards, the company I
worked for hired some engineers who worked in the aerospace industry.


We had them manufacture controls for industrial battery chargers and the
boards had to me modded by adding a few jumpers.


One customer did not like the looks of them though of course all was OK
electrically. Anyway, when I mentioned that to one of the engineers he
just laughed.
He said, "Battery chargers, heck we have planes out there flying with
green wires."
Soldering green wires is common.
The problem with the melting insulation is that you can't tell whether
you got a reliable connection among all the melted plastic.

The monitors in question used stranded wires with melted insulation.
You solder the joint, then snip the wire. The strands stuck out
in all directions, sometimes overlaying other parts or traces.
"Hoping for the best" was not attractive to the QC manager.
