What adaptor do you use for the transfilling? Do you have a welding
bottle(s) that you exchange? Most of the transfilling adaptors I've
seen are more than $100.

I got one from this guy: http://search.ebay.com/_W0QQsassZjohnclairowens
I got an extra yoke end so I can connect any combination of welding or
medical cylinders.

Also have another one I found used for a lot cheaper.

I don't have my own welding cylinder, I fill from a friend's. If I used
more I'd get my own cylinder.
