I have been learning to TIG weld, using my first fill of Argon gas in an 80 cu ft cylinder. It started of course at 2000 psi, but is now down to about 550 psi.
When I called to arrange to pick up a refill, the local gas supply shop told me it had a missed delivery his week, and so had NO Argon refileld cylinders available until next week!
I have been told not to run the cylinder down to no psi on the gauge, as that would create problems since the shielding provided by the Argon gas would become unreliable. I'd like to run it as low as I can given the temporary inability to get a refill, but don't want to hurt either my learning or my equipment.
How low can I run the psi in my Argon cylinder before I should stop TIG welding with it?
