Hello,
What is a common flow rate for the argon when MIG welding?

That depends on the material type and thickness. For thinner sheet steel, 75/25 mix at 20 cubic foot per hour would be typical. Straight Argon will narrow the bead and increase penetration. What are you welding on?

I'm looking into getting a setup and I'm trying to figure out how long a 20 cubic foot tank of argon will last. It looks like about one hour of welding.
You might be surprised at how long it takes to weld for an hour ... and depending on your welder , it might be a stretch to weld that heavy of material . I'm using a Lincoln WeldPak 100 (110v machine), and .125 is about as heavy as I feel comfy with . I'm lookin' for a used 220 volt/225 amp machine in the Memphis Tn. area ...
