guys that weld with c02/argon mix

Gas is the ****. No spatter like flux and no sticking like stick welding. Also you can do AL with gas and stainless wire, thats huge for fixing intakes. I believe tanks have different fittings for different gasses so you dont hook up some binary munition in your garage. I have a Dual Mig with regulator and gas trigger but havent used it yet as gas. flux seems to work for what I need at the moment. Raw exhaust pipes and 1/8 steel plate.
