Plasma cutting machine cutting process will produce noise, smoke, arc light and metal vapors, etc., causing pollution to the environment, in high-current cutting or cutting non-ferrous metals is particularly serious. Now there are several different equipment and technology available to reduce this level of pollution, in addition to water recompression plasma arc cutting, cutting on the water surface and underwater cutting is also an effective way to inhibit environmental pollution. Cutting on the surface of the water needs to have a water tank, water tank used to place the workpiece worktable consists of a number of orderly arrangement of spiked steel components, by these spiked steel components will be cut workpiece support on the horizontal plane. The plasma arc is surrounded by a curtain of water when the torch is in operation. In order to maintain a continuous curtain of water, a circulating pump is required to pump water out of the water reservoir and into the torch. When the water is ejected from the torch, it forms a curtain around the plasma arc.
