Re: bench top solder fume extractor
There are various schools of thought about fume extraction, and these are strictly my personal views, but:
- Even if you use solder with lead, lead doesn't vaporize at soldering temperatures. It doesn't even melt at those temperatures.. solder is what's called a 'eutectic compound' that melts at a lower temperature than any of its components. The risk of heavy metal exposure is negligible.
- Mostly you want to get rid of flux smoke. Fluxes are acids that aren't terribly active at room temperature, but get downright aggressive at a few hundred degrees. Rosin is the most common flux for electical work, because the really vicious stuff (usually zinc chloride) will eat through traces at room temperature if you let it sit long enough. Rosin smoke is basically a purified version of wood smoke.
- The amount of air treatment you need depends on the proportions of smoke and air for your average work session. For places with a hundred soldering stations going 10 hours a day, yeah.. fume extraction is an important issue. The average hobbyist soldering session doesn't put all that much particulate into the air though.
So.. with those points for background, I consider fume extraction at the hobbyist level to be a convenience issue, not a health issue, and certainly not a critical health issue. I personally use a small desk fan and expose myself to a hundred times as much similar particulate when I light a fire in the wood stove.
If you like the unit you linked to and are willing to pay the price for it, by all means buy it and enjoy using it. Dig into the details before spending money you really don't want to because someone has pressed the "eek! lead! fear!" button though.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
