AHP alphaTIG 200X. Anybody got one?

Yeah, well let's just say I learned the hard way myself. I've emptied out a couple of cylinders of various gases overnight by either forgetting to close the valves or saying "Ill be right back at this in the morning, so I won't bother closing the valves tonight". This was before I learned about the dual seating valves too, and would routinely only partially open the cylinder valves.  

Which reminds me... I need to get the Argon tank on my Syncrowave filled again.
