I currently have a simple 4" deep water table for my plasma cutter, and it works well but the water capacity is too small and gets contaminated very quickly.
So I want to make Version 2
I would like to make a separate air/water tank and use compressed air to force the water upto the table like I have seen others
A few questions :-
1) If I had the water outlet to the water table in the bottom of the air/water tank, and the Compressed air inlet and vent in the top of the air/water tank, what air pressure would I need to move the water upto the table?
I am thinking that if you go above atmospheric pressure (1 Bar) it would move the water???
I want to make the air/water tank from sheet metal, so I need to know the pressures involved.
2) What is the best method to stop the segiment getting into the Air Tank?
I could stick the water pipe 1/2" above the bottom of the tank, but I would like to be able to completely drain the water table.
Thanks in advance
