Welding smoke and fumes can be dangerous, but there are several types of equipment designed to clean the air welders breathe. Capturing airborne pollutants at the welding source is the most effective technique available. Common designs include source capture arms, portable source capture air cleaners, downdraft or sidedraft tables, and smoke extraction systems. Other air purification devices include ambiant air capture systems and breathing masks and respirators.
