Abstract
A pivoting door assembly for a downdraft cutting table assembly includes a door for covering a vent of the downdraft cutting table assembly, and an arm assembly coupled to the door. The downdraft cutting table assembly may include a cutting table for supporting a workpiece, a cutting torch assembly for positioning a cutting torch for cutting the workpiece, an exhaust duct for exhausting fumes, and a vent opening into the exhaust duct. The downdraft cutting table assembly may also include a slag removal system. The arm assembly is actuated by the cutting torch assembly as the cutting torch assembly positions the cutting torch over the cutting table. Actuation of the arm assembly by the cutting torch assembly causes the arm assembly to pivot the door open for allowing fumes from the cutting torch to be drawn into the exhaust duct.
