Why use a silly little power supply? Use your welder
I did that. Or rather offspring made the AC to DC converter bit for my old buzzbox.
Rigged up an old plastic dustbin. Used it to treat suspension components.
It was putting enough amps in to raise the temperature of the electrolyte to around blood heat.
I usually add a dishwasher tablet to keep the oil and grease in suspension. This helped to generate a deep and stable foam.
It was set up in the shed.
I try to restrict dirty cutting and grinding duties to the shed. One morning one of my son's friends was relegated to the shed for this, the rest of us were in the garage doing nice clean things. The bath had been bubbling away overnight.
We heard a dull BOOM and said friend came staggering out of the shed looking very pale.
The grinding sparks had landed in the foam
The foam is a perfect stoichiometric mix of oxygen and hydrogen.......
Shed roof still displays a slight gap to the end wall.
It still comes up in conversation every time said friend is encountered.
I have an old PC power supply with a bulb box for current control I built for plating. I also have an ancient variable voltage bench power supply I liberated from a skip at school. I just use these nowadays, there is no real need for such large currents.
I have set up a 'pond' from scrap timber for the frame and plastic 'tarpaulin' as a pond liner. Used that to treat the chassis of a old style electric scooter.
I have seen a video of a complete trailer done that way and often wondered about about doing the lower sections of a complete car like that. That might need such high currents.
