Default Bad bottle, again.

This is, really, getting old. Couple weeks ago I was in the middle of a simple project, gluing together a handrail for the front stoup. I was congratulating myself for the beautiful, shiny mild steel beads on the filets, as the gas was decreasing in the tank. Then, the tank was just a few pounds from empty, so I called the LWS. Told me a fresh Q tank would be in on Friday. Called LWS on Friday to make sure they had fresh bottle before driving 25 miles to pick it up. No bottles. Clerk said he had a stubby of Argon, so I drove to pick it up.

Hooked up when I got home and went back to railing project. Gas inclusion in beads, so I switched to aluminum. Hard to establish bead, carbon contamination, little to no etching along beads. When I attempt to introduce rod into the puddle the end of the rod, immediately, balls up, inside a glob of crud. Just junk. 2,000 psi, running at 10 to 20 CFH at torch. Only difference in setup was new bottle.

I've had several bottles with bad gas, but it didn't show up until pressure got to about 500 psi.

Does anyone have tips on a sure-fire way to test jugs for gas quality?
