I’m glad it turned out to be just bad gas … strange the way it looked. I’ve had moisture contamination before but never anything like you’ve encountered. Just upgraded from an 80 cf tank to a 150 tank … haven’t used it yet … I’ve always done business with Airgas I find them to be pretty good; only once have I found their info to be faulty … when they tried to convince me to use pure tungsten … my bad … probably should have specified I was using an inverter LOL.
