Steve: ­would like to show another explanation. The optical angle probibly
causes much of the beading, but consider another source STANDING WAVE
PATERNS , When an arc conducts across a distance some energy is reflected
back causing increased energy at one point and a null of energy at another
point. Cuttent flow is not pure DC flow but a flow of resonating power that
spans DC all the way to XRAY. An extream example of this is ball lightning
that  will create interfearance across all bands of an amature reciever and
can last for several seconds of time.
