I've recently started doing electronic repairs (mostly wiring) and need to shrink heat shrink tubing. A long time ago I bought a heat gun used for removing paint and used that. It was 120 volt, so I left it when I moved here.
I've never had much luck (or is it patience?) shrinking it by holding it over a soldering iron tip. Using a flame, like a cigarette or stove lighter ends up with burnt plastic. :-)
Is there such a thing as a small heat shrink tube shrinker that does not toast the things around it? The largest thing I need to shrink over is about 1/2 an inch most of them are small (20awg or less) wires.
Thanks in advance,
