The Negative lead goes to the rusty part ... Positive lead connects to a small piece of steel , can be stainless or galv. anything really .

I've found as little as 4 Amps works fine .. it depends on how big the part is and how close the electrodes are to each other .. Closer electrodes = higher Amps . Ideally, you want to surround the rusty part with the POS electrode ,this isn't easy to do in practice .

Watch the charger ... check it often to see it isn't overheating . If its pulling too much current , just move the Pos electrode away slightly .

After removing the part , wash it down with clean water and brush off the residue . I give the part a quick coat of that diluted phosphoric acid solution , before the air has time to recoat it with rust.
