TIG welder with HF start (25/04/11)

I was looking for some info on high-frequency/high-voltage start circuits in TIG welders for another application, when I came across this page. The URL had unfortunately broken, but I managed to piece it back together with the Wayback machine. I decided to mirror the page here, because it contains some very interesting info on TIG welders.
