Monty, any idea how much current
the derusting draws. I used one of the $3 Harbor Freight multi-meters in series
with my anodizing supply. It'll handle 10Amps. If the current draw is low enough
(which I suspect it would be if the process takes 24hours), you could use a
wall-wart as a supply.
Ernest,
The current is up to you. Less takes longer. There
is some point where more only heats the water. I just set my battery charger on
the 12V 15A setting. Now I know that there is no way this thing was drawing 15A.
It also worked on the deep cycle 2A setting just more slowly. The amount of
current the thing draws depends on the surface area of the anode and cathode. If
you have a great big anode and cathode it will probably draw too much current
and overload your battery charger unless it has some way to limit the current
draw. Somewhere I came across a link where a guy built a big plywood tank, lined
it with plastic and put an entire trailer frame in it. He hooked his welder up
to the thing!! Worked like a champ.
