Eric, I am an EE. I would try it myself, but I don't have a spot welder. DI water is very high resistance - essentially an insulator. But it won't stay non-conductive for long if you are welding in it. One of the electrodes is likely ground. To boot, you are normally connecting the electrodes to conductive sheet metal and no one is getting electrocuted. I would be more concerned about the energetics. I would just start with snapping the electrodes in a plastic bucket with DI water - or maybe distilled water to start. I would put the electrode bars through holes in a sheet of plastic so water cannot splash up into the welder. Doing this underwater I estimate to be a step forward over what Mills did; and simpler. When testing with a fuel pellet, I might encapsulate the prepared pellet in wax to isolate it - then crush through the wax with the electrodes.
Of course, if someone is uncomfortable with doing this, they shouldn't try it! Protect yourself!
