ABSTRACT:
A smoke removal device, especially designed for use in welding, having one or more portable funnels, with a wide opening through which suction may be directed to remove smoke from particular areas where combustion is taking place, and a narrow opening opposite to the wide opening, a vacuum device for creating the suction by which the smoke is removed, the vacuum device having an inlet valve for each funnel, and hoses connecting the narrow opening of each portable funnel to one of the inlet valves of the vacuum device. In a preferred embodiment, the portable funnel is connected to a base containing magnets. The funnel is connected to the base by a first cylinder extending downward from the funnel, with the first cylinder fitting inside a second cylinder attached to the base, with the funnel and first cylinder being rotatable in relation to the base and the second cylinder. A wheeled, multifilter carriage is provided to clean smoke coming from the funnel before it is exhausted into the surrounding air.
