CNC Plasma cutter machine made from a Torchmate kit has the ability to cut 4 foot by 12 foot full sheets. The machine includes a water cooled table with water level control to not only cool the cut steel as it is being cut, but also to keep air particulates out of the air. The machine, including the computer, software, and table are available for sale. I'll even through in a oxy-acetylene machine control cutting torch setup which I've cut 3 inch thick steel with. Contact me if you are interested in acquiring it.
