A cluttered and messy work bench with a short-arc xenon globe supported by "helping hand" metal clips, with one of their bases on a sheet of acrylic for insulation. Alligator clip wires run from the terminals of the globe. One the left the cathode is (incorrectly) wired to the return clamp of a TIG welder. On the right, the anode is (also incorrectly) wired to the electrode of a TIG torch.

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...
