As spring is approaching its time to dig out the mig welder again. So far I´ve been using fluxcore, but I plan on buying a gas bottle. So what gas should I get. My local supplier can get most everything. Cost is not that big an issue. Should I go for CO2, Argon or a mix (25% CO2)? I mostly weld thin stuff, up to 3mm (1/8 inch). only carbon steel so far. Any opinions are wellcome (just dont tell me to get a tig machine, thats not the kind of advise I need) Henning
