i just hate seeing fuji talk smakc like he was. I have been welding for years, their is no "small job". I still don't see how breathing in the by product is harmful, unless your welding lets say a peice of metal etc with paint on it. Which

A. paint blocks the connection between positive & negative = no spark no weld

B. welding paint = stupid, it can cause a fire.

C. I know of no metal regularly used metals that cause any type of lung damage. + also consider youcan wear a breath maks if this were the case, which is always availible at any placeo ffering welding etc.
