A size "S" tank is what.... 150 cubic feet? About 50" tall with the safety cap on?
So at 40CFH that works out to what.... 3.75 hours? (Yes, I suck at math.)
The sizable hiss you hear when touching the pedal could just be you hearing the gas solenoid opening in the machine when starting it's "pre-flow" to the torch head and you get a "burst" of gas flow. Although it would be a good idea to check all of your gas connections with some soapy water to check for any leaks to be on the safe side.
Another thing to remember (on non-fuel cylinders) is to open the valve on the tank ALL the way to prevent leaks past the valve stem on the tank. The inert gas tanks have valves with TWO seats in them - one to shut off the tank when closed, and one to seal off the stem when FULLY open and seated at the top of the valve. It's different on FUEL cylinders (Acetylene, propane, etc.) where you only want to open the valves slightly so they can be turned off quickly if something bad happens.
Congrats on the new welder purchase. Let us know what YOU think about it.
