"You're doing it wrong"Chthonic confesses: "Only last year did I discover why the lids of things in tubes have a recessed pointy bit built into them." Tell us about the facepalm moment when you realised you were doing something wrong.

Plus, lead melts at 327 °C and boils at 1749 °C.So unless the iron is really fucking hot, it's not vaporised lead that's causing him to sneeze.

solder, being an alloymelts at much lower temps depending on the tin and antimony content. Vapour phase soldering makes use of the fact that you don't have to vapourise all the solder, just give the spread of energies in the average distribution enough oomph that at the top end of the distribution there is enough for SOME to evapourate. Else the triple point of water would be ridiculous, i.e. water at 0c can be either ice, water or vapour.

Some, but not a lot.Regardless of whether or not been it's alloyed, lead has a very low vapour pressure, even at the operating temperature of a soldering iron.

SolderSolder comes with flux in it, which used to be rosin based... smells nice-ish but turns to acid in your lungs - and that's what's making you sneeze. There's no lead vapour.
Ditch it and get some fresh solder with a modern flux and you'll be fine. (Don't care what they say about lead-free being more eco-friendly, it's still crap, tin/lead is what you want!)
