I have never seen this many warning signs on anything that I have ever bought. I know that I'm supposed to suck away the soldering fumes, even if I use lead free solder, which I'm going to do with a 12 volt computer fan fitted with a carbon filter. But what the heck is in the flux that will damage my nervous system... ๐ putting my mask back on... ๐ท
Copy that! Looking up recommended temps for my solder, the iron model and work type.
Just FYI this is a hugely overstated risk. You can melt leaded solder with a Zippo (~350F) while lead only begins to produce a tiny amount of point vaporization at ~900F, so the safe range for your iron's temperature is large.
You're doing the right thing setting your iron to match the solder. Beyond that, just thoroughly clean your station and wash your hands after you're done.
Separately, I don't think rosin is all that harmful, but it's certainly very irritating if the fumes get in your eyes. Your basic fume hood should be more than sufficient.
