Jack, can you make a voltage measurement across the electrode you have connected to the positive supply terminal? Place your probe as close to the electrode as possible without touching it on the side that is opposite to the location of the negative connected electrode. The other probe is should be connected to the same electrode in a location out of the bath. I used my supply terminal as the drop was minimal.
I noticed a large voltage drop earlier which suggested that joule heating was occurring within the coating on the electrode.

I think it is somehow resistance heating through the borax or chemistry with creating boric acid. Just a speculation. I had heat >130F (I say it this way because my thermometer was electroplated or something causing it to register 20F too high. It read 158 or so at the max). To get more heat, you need an anode with as much surface area as your nickel. I used 12V at 1 amp.

It has been running at that current level for more than 12 hours now and no anomalous heat has shown up yet. - Has anybody been able to replicate Chuck Sites results? I have not seen any claims to that yet. - Paul
