I hadn't used my TIG welder for a little bit, and when I tried to weld, no gas would come out no matter what. I opened up the welder and thought maybe the solenoid broke or something. So I tried to bypass this internally. When I tried connecting the gas line directly to the output (it's one of those things where the output and the gas line is the same) no gas would flow out either.
So I poked a screwdriver into the gas port to see what's up, and it turns out there's something jammed up inside that that was preventing the gas from flowing at all...
Something to watch out for if you wonder why no gas is coming out even though your bottle is full. It seems something got up into the gas port, and it got stuck inside.
Probably a bug or something, that's what it looked like.
