- More likely, the soldering flux is what you're noticing as a sticky
- paste. It takes 300F or better temperatures to melt solder, so unless
- you're getting pressurized live steam out of your faucets, you're
- nowhere near melting it. (Incidentally, they aren't welded--welding
- copper is lots more difficult, and couldn't be done cost-effectively
- enough for plumbing. Doesn't seal as well, either.)

- If it really bothers you, you can clean the flux off the joints with
- a solvent (denatured alcohol should work) so it doesn't get sticky.
- Otherwise, don't worry about it.
