I’m using sterling cool and love it! It keeps the table rust free and the water clear as day. I have a tank under the table that it drains into then I use compressed air to push it out of the tank back to the table. Tons of examples/thrreads on this forum. I can’t be bothered with borax and the rest of it. This is a set it and forget situation. It’s not really that expensive if you think about how long it lasts.

I used a basketball hope base on my Pro to drain coolant into w/a harborcrap 110-volt pump to pump water back into table.
My XR I have 70-gallon tank that I drain into.

This is the answer back from Chem World:
“Our Chemworld 830 is not recommended for Plasma Cutters. It has been designed for closed loop water systems.”

I’m a bit late to this thread but I was about to cook up a batch of this to try it out and was wondering if anyone has replaced the dye with copper sulfate pentahydrate? it should turn the fluid a deep blue and control bacteria. Copper Sulfate is a biocide that kills algae and plants. May not be as effective on iron loving bacteria, but I haven’t researched it.
Are you sure you want to do that? Here is the SDS sheet:
And here are a few excerpts from it:
Sulfur trioxide will combine with H2O to form sulfuric acid.
no, I am not sure at all. in fact, that’s a big reason for my post.
at the concentrations I’m thinking of it seems very unlikely to form SO3 in an aqueous solution. there’s a few other cupric compounds that i might try if I end up with H2SO4. I’ll give it a shot an report back. if it does form H2SO4 if might save me a bit of money on buying it for my electroplating bath.
Sterling Cool. Just buy some and be done with the science experiment. @ChelanJim is correct. It will make sulfuric acid gas during the cutting.

Can’t stress that enough.
Just buy the proper additive - not worth risking your health to save a few dollars, especially after spending thousands on equipment.

For years I have been using Plasma Green 1050 from KCI with the anti-freeze that they also sell for plasma tables. Works great!
