    Controlling the over-exposure of welding fumes is not an easy problem because neither general nor local exhaust ventilation systems could be successfully applied. the study has been experimented to give possibility to give possibility to reduce the exposure level of welding fumes. The jet air stream pushes the welding fumes away from the breathing zone by using the frictional characteristic of jet. Laboratory experiments were conducted to optimize the efficiency of controlling welding fumes. Thereafter, its performance was tested in the windless booth and an industrial field. The efficiencies of reducing the welding fume exposure were about 92% and 43% in a laboratory and an industrial field, respectively. Additionally, it resulted in elimination of heat inside the mask and enhancement of clear visuality. Also the mask didnt give a welder inconvenience.
