For those that did not know again this is good information. The thing you run across in cars is galvanized steel and other propietary metal coatings. If your not positive what your welding on ask somebody or check. You do not want to weld on this stuff anyways as the weld can be so contaminated that it has no strength mind the safety hazzard. Anytime the arc is doing something unusual like going off colour or making excess smoke you are getting an important clue that something is unusual. That said the benifits of proper application of welding technoligy are enourmous. With care and understanding you can do work at home that is not substandard and not a safety risk. Plus since you do not weld all day for a living you are not undergoing long heavy exposure as even the byproducts of normal welding are not particularily good for you. Just my two cents worth. Would never be without my welders, plazma cutter etc. Come to think of it another liability of working on our cars is the fire risk.Just think before you apply a weld to an area is really about all it takes. Plus have a really good fire extinguisher handy. I prefer the larger halon units as there is no after residue (white powder) but not able to get refils now. Think the stuff attacked the ozone layer. But it was good.
