Rust removal question

[flyboy2610]

I have a question about this method of rust removal.
http://www.fordification.com/forum/viewtopic.php?t=2391

I have a battery charger that will charge at 2 amps, 12 amps, or has a setting for 75 amps to use for starting an engine. It is a Schumacher battery charger, if that makes any difference. I can hear a very distinct hum when it is on the 75 amp setting.
Here is my question: Has anyone ever tried to remove rust with their battery charger cranked up that high? It really gets the water moving almost instantly, but I wonder if it would harm my charger? I haven't tried it for more than a few seconds. I don't want to damage anything, but that would sure speed up the process.

i dont think it would do any thing to the charger but you could just sand the stuff if you dont want to risk it.

It works fine using it at 12 amps, but I have a couple of parts that are pretty rusty, so I was wondering if cranking up the charger (which would definetly speed up the process) would damage anything.
Thanks for the reply.

if you done it quite a bit for long periods of time it could burn the charger up. short periods might be ok but i wouldn't do it more than three or four times.

I don't want to burn up the charger. I guess I'll just put a part in when I get home from work about 4:00 PM and take it out when I get home from work the next day.
Thanks all for your replies!

that sounds too long to me. but i really don't know all that much about chargers. i know if you get a real good one they can be made into arc welders but you have to get the right ones.

This looks like it would be a good way to remove rust from intricate parts such as bolts and hood hinges.....jacks etc. The possibilities are endless.
