I bought a Lincoln 175 pro sq wave unit a couple of years ago and have enjoyed shade tree tig and stick welding. I just bought a 350xmt CV/CC with a S64 feeder and a Bernard Q300 gun off eBay so I'm going to start exploring MIG and higher power stick welding.

I have a large Argon bottles with a ball/flowmeter. Can I just buy a CO2 bottle and a CO2 flowmeter then T the two flowmeter outputs into one output to my XMT? Could I then custom adjust my mix ratio at will?

Thank you
