Passivating stainless steel with phosphoric acid

I need a small transformer to passivate stainless steel by hand using phosphoric acid. I need one.

Sorry, I haven't heard of that process so I don't know what size and type of transformer you need.

Rick,

Passivation is performed using citric or nitric acid, not phosphoric. Nor is electricity involved in the process, unless you were really thinking of electropolishing. Let us know if we can help.
