12/2020 HydrogenGarage.com Every Hydroxy Gas generator cell that comes out of our shop has been professionally cleansed. Under Bob Boyce's approved proprietary method. All oxides and dioxides of iron, nickel and the worst one chromium oxides, has be cleansed out of the cells. It is a proprietary method that Bob Boyce discovered years ago. This mean you cells will not foam and the yellow chromium oxides are gone out of the cell. Chromium oxides present in your cell will prohibit the ortho spin state of HHO gas to happen! If your water tank ever turns a yellow color, flush it out and make a new batch of electrolyte water. (10% NaOH to 100% weight o f water) Use only distilled water or R.O. filtered water only! No tap water, too many chemicals. For ice truckers use a 20% mix.

He calls building up catalytic layers on the plate surface area. You start the first day at 1 amp, next day of driving 2 amps, the next 3 amps, etc up to the amp draw recommended for your cell. S7 Cell - 3.5 to 5 amps. D7 Cell - 5 to 10 amps. S16 Cell - 9 to 15 amps. D16 Cell - 18 to 25 amps Dual D16 - 20 to 35 amps ( this larger cell is coming soon, 9/24) Series cell SS plate prep. & conditioning by BB ( published version, not his proprietary version) https://www.hydrogengarage.com/plateprep.html
