I have an old transformer type 10/2 battery charger that makes clean DC power. I always run it on the 2 amp setting for electrolysis. Actual amps flowing depends on how much metal is in the tank. Small parts flow less than 2 amps. I've seen close to 10 amps with something like an oil pan. Lots of surface area can overload the charger, so I check on it to make sure. All that is needed for the process to work is current flow. More amps just wastes energy and produces more of those flammable bubbles.
Really rusty stuff might be left cooking overnight. Most things have dropped most of the paint and turned rust black in a couple of hours.
Many newer battery chargers do not make clean DC. Any AC component that goes into the tank slows the process. For those types of chargers hook them to a battery like you normally would to charge it, then hook the battery to the tank.
The two big positives with this process is no toxic waste to clean up and it is nearly effortless. A stiff bristle or wire brush can be used to help knock loosened paint off when I'm in a big hurry.
