On: Have you ever seen soldering this close? [video]

There is no lead in the solder fumes. If anything, lead-free solder is substanially worse, since the flux used for lead-free solder is a lot... harsher. Either way, this can be largely fixed by a small fume fan.

Thank you. In fact, I drive a small horizontal quadcopter propeller with a 3.7v LiPo while soldering to pull the fumes away.
