Recently purchased a PlasmaCam 4' x 4' table unit for our High School Welding Shop. We will run a Miller Spectrum 875 on it. It just arrived a few days ago, and we're still at the assembly stage. Because we will not be using it EVERYDAY, but more for special projects it won't have it's own dedicated fume exhaust system. I was thinking that a WATER TABLE might better suite our uses? Any suggestions or ideas?? I was hoping for perhaps some plans and or photos of some water tables manufactured for this unit?? Thanks
