I use a small fan to suck the fumes away from my face and a HEPA filter to trap any particulate.Works great even when using a torch to solder parts together or using a solder pot and dipping wire leads..I have also noticed that the "non-lead" variety of solder has a tendency to crystallize after just a year or two and develop high resistance and "noisy" joints!Maybe that is why so much of the equipment made in Europe, Japan or China tends to fail after a few years of operation..Dan"Everything that glitters is not necessarily good."

It's not saying anything new, we all know chewing on the solder is a bad
idea.
