I've just commisioned my new and larger electrolytic rust removal bath. It uses 8 lengths of angle iron as anodes, as I had a bit of angle iron left over. They give plenty of line-of-sight coverage. My old set up was smaller and with 4 shorter angle iron anodes powered with my 4 Amp 12V battery charger. I could only do one side of the Optimus 182 pot holders at a time and it drew 1.7 amps.
So I built the new bath, and yes it can do both sides at once at just under the 4 Amps. But, bless the battery charger if it isn't really rated at a continuous 4 amps at all. Afterwards, and in small lettering I noticed it stated 2.5 Amps. At 4 Amps draw it's thermal fuse clicks out when the unit heats up, and cyles on and off seemingly happily. So now I've got the pot holder half out of the cleaning solution, doing half at a time.
The outer flame spreaders have been de-rusted a treat.
