Re: Old dog learns new trick...Welding!
I purge the gas out of my machine by squeezing the trigger on the stinger with the machine turned off. It is also how I purge air out of the line when first turning the gas on before welding. The gas valve on mine is a manual type inside the stinger. If yours has an electrical gas valve inside the machine, I don't know. Perhaps that would be in the owner's manual?
Both meters that I have are a meter/ regulator all in one. Both are also analog dial type as well. They have two gauges on them. One gauge for the tank pressure and one gauge for the output volume. One knob to adjust it.
