Abstract
A process and apparatus for absorbing and exhausting efficiently dust (oxide particles), fumes, smoke, harmful gases and the like generated by plasma-arc cutting. The lower space of a fixed board for supporting the material which is cut is divided by plural partition plates to the direction crossing at right angles with the driving direction of the cutting machine body, an absorbing hood connected with a dust collector through a duct is installed and fixed to the cutting machine body in order to exhaust from the side of partition space corresponding to the plasma-arc cutting torch, fumes in each partition space at every position of cutting at the shortest distance and efficiently by making the absorbing hood move together with the movement of the cutting machine body. A reduction of the dust collector's capacity and a simplification of the accessory equipment are possible and cost reduction of the equipment for exhausting smoke including dust, fumes and the like in the plasma-arc cutting machine is possible.
