We got a small project from SpaceX. They need NASA approved pure water for their Dragon Capsule Program. The unit we made will produce the drinking water that goes into space to quench the astronauts thirst. The frame for the purification unit is made of 6061 aluminum strut. I used 3/32 4043 welding rod, E-3 tungsten 3/32 dia. with the amps at 150. The 3rd photo is a stainless frame for another job just to give an idea of what goes on the frame. That would be some pre filters a UV sterilizer and some post filters and the electronics to control it all.

Argon, about 22 CFH. I'm using a #6 cup with a gas lens. Normally weld stainless that's why I've got a gas lens on the torch. And yes Ryan this machine weds real nice. Salesman talked me into the fancy pulse panel said it would make welding thin material easier. HE LIED. Unless your running an automatic welding process that panel is a waste of money.
