That looks like it is something I could use. How about some more details about the process. What is in the liquid, what kind of metal is the electrode, and which one gets connected to the positive electrode. I assume you are using DC current.

If you Google for Electrolysis, you will find a ton of information.
The solution is water and 1 tablespoon of washing soda per gallon. (Arm&Hammer Washing Soda is available in the laundry detergent aisle at the grocery store. NOT backing soda.)
The electrodes on my setup are a couple pieces of flat steel bar and a coat hanger. I used a coat hanger to hold the piece I was cleaning. Connect the negative lead to the part (coat hanger) and the positive to the steel bars. The steel bars (positive anodes) are connected in series. I have 2 anodes, but you can add more.
Remember that electricity flows from negative to positive and this is the way you want the rust to go (away from the part).
When you connect the power supply (battery charger or other source) you should see the solution start to bubble. If it doesn't check your connections and power supply.
I believe the bubbles that form are hydrogen, so make sure to do this in a well ventilated area. I did it outside.
Clear as mud? It's really pretty easy to set up and I've seen where people have set up tanks large enough to do table saw tops! The process takes several hours. The piece I did "cooked" for about 3 hours and I could have probably let it go longer, but it was getting late. I've also seen where people have used this method to clean old hand saws and such, because it won't damage the mfg's etch.
Oh, yes it is DC current and most folks are running 5~10 amps. Less will work, but it'll take longer.
