ABSTRACT:
A water table for a thermal-cutting machine, especially for processing aluminum, with an underwater plasma-based cutting system, with a surface that is immersed in a tank of water and that supports the material, and with a device for raising and lowering the level of the water. The inner surfaces of the side walls of the water tank slope in below the surface that supports the material. A forwarding gutter extends along the bottom of the tank and accommodates an apron-type conveyor. The upper strand of the conveyor extends through the front wall of the tank and up through a water-tight duct to a container that accommodates the coarser particles. A sludge trough is positioned below the gutter at the end that the bottom strand of the conveyor travels toward. A device for raising and lowering the level of the water includes an inflatable cushion located in the tank and under the water.
