Post pics of your purge setups. I'm thinking of running a line mounted to the table with an on/off switch with regulator in the table for easy access so I dont have to constantly go to the tank.

 

That is exactly what we have where I work. Works great, do it

 

My setup is basically a -4 AN line from the dual regulator to a Swagelok valve mounted to the table. Works great, I really love having access to the valve right there. I can even lower the flow by watching the ball valve and adjusting the valve for when I get to the end of a runner ...

 

So simple and smart. Im gonna have to set that up at the shop.

 

looks ****

 

I like the switch idea, I do keep my bottle right next to me but its still a pain to reach up. Im just running a single 330 tank to reg to a large gas lens. I have different blocks for my head flanges each are tapped to accept the lens with plugs for the rest of the runners. I also have block offs for all wastegates and flanges to go along with it. I need to make something so when im welding up a wastegate elbow to flange on the table it will slip over it or fit into the id of the pipe, tape or aluminum foil will melt onto the small peices when welding them.

 

I use rubber stoppers with holes in the end and also the round rubber covers that you slide on chair legs to prevent them from scratching the floor, in the ends of the tube in order to set up a purge when welding.
