Abstract

Suction nozzle of the removal of fumes, gas and vapours during welding, consists of a long profiled tube provided with a longtiduinal slot between two edges turned inwards; the length of the tube is adjusted telescopically at one or both ends; in the middle of the tube is a pipe leading to a suction fan, or the fan can be connected to one end of the tube, the other end being closed. The tube pref. has a symmetrical cross-section with a flat outer surface on at least one side of the slot; and the two edges forming the slot are pref. at 80-90 degrees w.r.t. each other. The nozzle is portable and can be adjusted to suit a wide variety of welding operations, where it can be located by magnets and adjusted telescopically to the length required.
