ABSTRACT:
A water-filled cutting table for a plasma-arc torch cutting arrangement is configured having a plurality of self-extinguishing and combustibly non-supportive slats oriented on edge and transverse to the direction of travel of the torch arrangement. Magnetic grounding elements are also provided for electrically grounding each piece of product to be cut. The use of self-extinguishing and combustibly non-supportive materials for the product support slats drastically reduces the amount of undesirable slag build-up on the slats which had heretofore created problems of proper product support and, consequently, decreased product quality.
