I returned the small annealer and went for it - bought a Chili-Pepper kiln. I tested it out today and it seems to work fine. But then I tried to light my torch and my oxygen valve on the torch seems to not be working. I can turn it and turn it until it comes off and still no oxygen. I tested the tank and the line and both seem to be fine. I'm unable to talk to anyone in support until Monday.
It's going to be a long weekend...
