So the inside does not get back welded and ground like this then http://picasaweb.google.com/kevin.ladue/KegglesForClubMembers#5194106467776001890.
No need to if it's back gassed it's already smooth.

My thinking to face off the coupling end removing the external radius then machining a reduced step to the thickness of the keg with a snug fit.
My Synchrowave's limits are 3 to 385 amps output.
I dont think I have ever welded anything that thick with my tig but aluminum.
I do think you could weld a keg with 1/8th inch once you got your amps right.

What pulse rate?Have you tried pulse at 100% / 70% current, it makes it easier on the inside when back welding the couplings.
Yeah, definitely could, but I don't have my hand in it enough to go with anything but the 3/32", that's what I am used to. What pressure do you use when back gassing?
You can also put in a Y at the regulator. Use a Y with valves so you can adjust flown and easily turn off the Backgas side when not needed.

I got a "T" for before the flow-meter from my local welding shop and bought a cheap flow-meter off eBay. Total about 40 bucks. I was afraid of not being able to control the flow ell enough if I only used a Y after the flow-meter.
That is even better. I was going on the cheap.
Hi Pat. Yours is the best solution of course. My idea is the down and dirty way to get the job done. My hose is plenty long. As far as I'm concerned.
Thanks Pat. Now I have to scrounge up another bottle, wish the mig wasn't argon/o2.

Ya I heard you guy"s from Iowa where built that way !
