I started looking for an additive for my plasma water table long before I started my build, and now that I have my table up and running, I still can't get my hands on this "mysterious" additive.
I see members posting recipes using Sodium Nitrate, but that stuff turns into a carcinogen when hit by the plasma arc, so I refuse to use it !!
I got hold of Praxair this morning to see if they could get anything, and they called back after speaking to their "Sales Tech Guy". They want to sell me Hypertherm part# 028872.
I don't think this is the right stuff, because I think that this product is a coolant to be used inside the torch handle to keep it cool ( like a water cooled TIG torch)
Does Hypertherm really make a product for water tables, or is Praxair blowing smoke up my anus?
