Hello,
Wondering if someone might be able to help.
I'm using an 850watt power supply that can handle 70 amps on the 12v rail for rust removal (electrolysis) of larger than average items. In order to do this, I opened it up and combined ALL of the 12v wires and GND wires so that I have enough to handle the amperage without starting a fire. I also added a 60 amp inline fuse right out of the case to ensure I don't hit the 70 amp maximum draw.
My issue is that the current draw is based on a few factors but size of object and number of electrodes is one. The best way for large electroysis that I've seen is using a manual battery charge or DC welding supply, however, the first is harder to come by since most are automatic these days and the second is expensive.
My question is this, is it possible to limit the maximum current that the power supply will deliver rather than let the load pull as much as it wants and then trip the unit when it goes above? I ask this because I am hoping to do a larger item than I currently am working on, however, based on what I've seen, I imagine it'll pull more than 70 amps. With how electrolysis works, I don't need that high amperage anyways, but I need a way to limit it.
Thoughts?
