Stop in for a cup of coffee

So if you is welding for an hour or so, and its leaking, would you not want to know? Thats the point. Free welding gas.
Last place I worked, I got a new welder. I was the only one that used it and I was sure it was tuned off when not using. 1st tank went WAY too fast. Turned out the cyl fitting had a nick in. They gave me a free replacement and it lasted months…
