Trying to run a short-arc xenon globe from a TIG welder. It didn't work.

Apart from the wiring mistake (negative/TIG electrode should go to the pointy electrode in the globe), the HF start on my unit wasn't enough to strike the arc.

I wasn't optimistic going in - the HF start spark on my welder is only about as long as the electrode spacing, but AFAIK these lamps run at several ATM pressure so more voltage is needed to get started.

Looks like I'll have to make my own power supply...
