The metal vapors (like most other vapors and fine particles) are a cancer risk. I don't know the level of risk. For hobby welding, I'd guess it's similar to smoking in that the more you do it the higher the risk of health issues.

What sort of mask do you use Malcolm? I don't think there would be
much room for anything more than a basic dust mask ('standard' white
mask) under my helmet. Is that good enough?
A dust mask won't help much. An inexpensive twin cannister style mask is a much better option as you want to filter GAS not DUST.
You can buy welding masks which completely envelope your head and incorportae a filter system. Others allow for an external breathing air supply. Both are EXPENSIVE !!
Normal ventilation should be adequate for hobby welding BUT be very careful when welding any galvanised metals. At the least these fumes will give you welding 'shivers' after a days welding, at worst a brain tumour ! Paint and other surface coatings can also produce nasty stuff when burned. NEVER weld on an empty stomach. Drink a milk based drink before you begin and have something to eat.
PS: The vapours from your own burning flesh, hair or clothing don't smell that nice either :shock: :shock: :shock:
Yes, the fumes han be pretty nasty, a good quality mask is a good idea.
Also be extra cafefull if youre welding any galvanised surfaces, thats exceptionally nasty!
Another consideration is the UltraViolet and InfaRed rays given off from welding, which can also cause cancer.....
i found some disposable masks that is specify fore dust,lite vapor and metal fumes. thy work well and are reasonably cheep. like th paper dust mask just 3times thicker and with a valve
