Plasma, Dry cuting,
I am changing out my table top with a tub to plasma cut the steel AT or under water. I have read that some run the water right up to the bottom of the steel you are cutting or just to the top of the steel. Does it matter how deep the steel is in the water, I know to a point, but if it is just under the water 1/8 inch or less. and Do you need to start all over on the settings, now that the steel or tip is in water.. I have seen some run under water 1/2 inch. The old shop I worked at long time ago. Running a very large plasma table. The tub I had made is made out of Alum and is 5 foot by 9 foot by 3 inch tall. I will put a 1 inch slats of 10 ga steel in an back and forth S pat. I have a tank to run air in to push the water up into the tray to the bottom or top of the steel. I hope this takes the warping out of the large pic's I cut, I have great cuts now. will it make the edge better looking too?
Pics to come soon.
