About 97%, http://www.mig-welding.co.uk/forum/...riced-helium-shielding-gas.65033/#post-838714What's the purity level on balloon helium then?
(I could google it, but that would destroy the conversational aspect )
Apologies. I was a bit out, welding helium is 99.996% pure or greater. Balooon helium is around 98-99% pure although BOC don't give an exact figure. I'm pretty sure balloon gas is usually recycled from MRI and cooling applications.

Straight He also gives the HF start a much harder time because of it's higher ionisation potential
