ABSTRACT:
A portable welding ventilation system for extracting harmful welding fumes away from a welder without requiring the welder to wear an uncomfortable respirator. The inventive device includes a seat having a plurality of air nozzles, an exhaust fan, and a pair of side members removably attachable between the seat and the exhaust fan. The air nozzles within the seat release pressurized air toward the welding area thereby pushing the welding fumes away from the welder. The welding fumes are thereafter drawn into an intake manifold of the exhaust fan and then released a safe distance away from the welder through an exhaust tube. Flange about the intake manifold reduces the amount of fresh air drawn into the intake manifold.
