I have heard both ways on better and worse on thin panels. Will try -- I think OK for thin also.

Z, KW --- I made the leap. I now have a 20 lb tank that measures like propane as the tank has an amount of liquid CO2 in it. For welding it feeds gas to the regulator. As I understand the regulator pressure gauge will read about 700 until the liquid is near gone then it drops kinda suddenly. It is not like argon mix which is all gas in the tank. Weighing it would be a better gauge if you want.

A 20 lb size steel Full Co2 tank weighs around 51 lbs and about 31 empty. Aluminum tanks are like 45/25. I got a 320 to 580 adapter to use an argon gauge - $19 on Amazon. Flow settings are about the same.

I was welding with .030 on 18 and 20 gauge sheet metal. I usually use .023 - .025 but tried the .030 first. Once you find your setting, welds fine and spatter did not seem much more than the mix. I am still playing with the inductance setting.

Correct anything above that is wrong.
