Who sells hookup wire that can be soldered without stripping? Typical use is reworking pc boards. Some magnet wires are of this type, but solder at too high a temperature for easy use on a pc board. The ones I've tried will loosen the copper if joints aren't made quickly.
Any suggestions for a maker or seller for a wire in the 26 guage range would be appreciated.

I use #24 teflon-covered wire. It resists solder, but can be stripped in tight places simply by "pinching" with needle-nose pliers... very handy for making tight PCB reworks. At GenRad we called such boards "blue-wired" for the color of the insulation.

Thanks Jim - I'll give that a try. There's some thermocouple wire handy that'll serve for a test.

I've used kynar insulated wire wrap wire like that .. the insulation melts easily under soldering heat, and the wire is available in 26, 28 and 30 AWG. Find it at most outlets and catalog distributors.
Cheers!!!
For prototyping work I often use enamelled copper wire in 26swg or thinner. The coating that works best for me is the pinker one. It is even easy to solder down at a kink in the wire for wire-through connections. The trick is to just tin the very end before putting it down to the board.
Note that some of the enamel coatings are not so easy to burn off.
Thanks Dave. I tried that this afternoon with another brand of
30 gage wire-wrap wire and it worked. I've put a roll of 26 gage Kynar on the list.Hul
I'm not entirely sure if this applies to the finished insulation; the msds refers to the raw pellets. I expect that it does, but don't know the risk level relative to say flux or any of the other junk we burn and breathe.
I hacked a wire wrap tool to do this. A WSU-30M:
