Abstract: A welding booth is described that is comprised of a plurality of individual welding compartments that are gathered in an elongated rectangular cluster. The compartments are joined by a common longitudinal air receiving plenum that leads to a central single upright exhaust stack. Each booth includes a vent screen through which air passes to exhaust fumes from the compartments. The compartments are defined by a central longitudinal wall that extends the full length of the compartment cluster and by a plurality of transverse side walls. The lower edges of the walls are spaced a distance above the floor to allow free communication of air between the compartments. Flexible curtains are provided over the front openings of the individual compartments with the lower edge of each curtain spaced above the floor surface such that outside air may be drawn into the individual compartments from the area beneath the curtains.
