Man , that question is just fraught with possibilities !
To clear up any possibly salacious answers , I'm talking
about the bottle pressure og my argon shield gas for the
TIG welder . I'm down to around 250 psi on the gauge , and
I thought it would be enough to weld up a bracket for the
rooster weather vane I made for my wife - not really as a
gift , but just because I knew she'd like to have one on
the house . Anyway , it turned out that my welds were very
porous , almost like the slag from a OA cutting torch . I
finished the part I was working on with the MIG so it was
really no big deal , I just saw a chance to practice with
the TIG .

Are you using a flowmeter with a vertical tube and a steel
ball inside? That's the best one to use. phil k.

Single stage regulators as commonly used for shielding gas have the
output pressure rise as the input pressure drops so it might be that you
have excessive flow causing turbulence and drawing in air due to the low input pressure, do you have a flow meter on it. No reason you shouldn't
get correct shielding with 250psi in providing the regulator is adjusted
to suit.

Yes , but it was acting erratically today . That's part
of why i think it's time for a fresh bottle . This one
only lasted me 5 years ... I don't weld much .

I have seen that affect with OA when cutting right down to the end of
the bottle.

I use high quality ball type flow meters on my argon and C25
cylinders. I can run a cylinder down to 30 psi before the gas flow
gets wonky. I usually don't let the cylinder pressure drop lower than
50 psi though.

After discovering that the steel I was welding was the problem , IYeah, no sense in wasting gas you paid for.
decided to wait until mine gets that low .
