TIG backside purging advice?

[GregWeld]

Go to your local welding store, take your current rig (just remove it from the bottle) with you.... tell them what you're trying to do. They'll help you set it up. Most all the welding stores I go to have lots of plumbing and adaptors for different regs etc. Since none of "us" can see what you're working with it's pretty hard to try to design something for you and tell you what you need. A quick trip to your local experts is going to get 'er done and save you lots of time and hassle.
