DC Power Supply for Electrolysis

[Dylan W]

I've got a few cast iron pans that need cleaning up, and electrolysis seems to be the best way to do this.

Plastic tub, steel sheet as anode, and sodium carbonate as electrolyte.

Most people on the internet use a manual car battery charger that puts out anywhere from 6 to 100 amps @ 12V. Battery chargers are $50-100, though, which is expensive for what's basically a one time use item.

It occurred to me that a basic DC power supply could be used, like this one:

My only concern is that the supply will have current limiting built in and not want to start up.

Thoughts?

Can't tell you why, but all anodizing lines I've seen had linear supplies. Maybe they were just old, but...

Why not just use a stabilized-current output supply (e.g. for LED-lights), and then be a tad more patient waiting for the result?
