Just a quick comment.  I suspect the electrode diameter probably has some
optimal value in relation to the gap distance.  With 1" and a narrow gap,
surely hot gases will tend to build-up in the gap and perpertuate the arc ???

Then again, too narrow & you won't have the heat transfer capabilities.

Would be interested to see one of the clever chaps measure a range of tip
diameters at a constant gap distance.
