For some reason that has been driving me mad, I can no longer run a clean bead on aluminum with my Diversion 165. The results after many attempts is nothing but what looks like chicken poop. I have tried running beads with and without filler on edges that I welded last year, covering the year-old shiny beads with the cp.
The latest bad results look like there is no cover gas, but I've checked all exposed hose connections and fittings for tightness, to no avail. My gauge reads 500 psi of straight Argon - the same bottle that yielded good welds last year.
1. Is there a quick and easy way to test the gas delivery system for leaks from the tank to the gun nozzle?
2. Can gas go bad inside the tank after several months?
Any help will be appreciated.
