In alot of shops that i have worked in they have some kind of what we call "smoke suckers". it is prity much a large vacuum with filters in it. Or they have welding helmets that have a fresh air pump that forces air in to the helmet. Sorry i dont have a picture of one right now. If you want i will get one. The only bad part of it is that there expensive! The one i have was $1500.00! Luckly i didnt have to pay for it my work did. If you dont do ALOT of welding its hard to justify the cost. But if your welding alum. or galvanized you almost need one. Or you could use some kind of blower to suck the fumes away from you. I made a vortex blower kind of like the Dicen fans. It amplifies the air pressure that you feed it. Dont know if that helps at all but just some other suggestions for you. If you want to see any of these let me know and i will get some pictures for you.
GIHAHIH!
