Hi All,

I am still a novice tig welder and I am changing out my argon bottle for the first time. It seems like it did not last very long. I do not have a flow meter and I think that may have contributed to it quick demise. With the regulator I had it to about 40 psi. Can someone recommend a flow meter to use with my machine? What flow do I need for steel and Aluminum? Also, question about the gas lens. Do they reduce the amount of argon used and can they be used for general purpose welding?
