question on welding gas
im abit confused on what type of gas i should buy, because they tell me there is straight argon and theres the mix. I mean what kind of gas do i need to weld both aluminum and stainless steel. I know this sounds like a noob question, but i would really appreciate the help.

We use full Argon on the miller synchrowave 180sd for Aluminum and Stainless and We use an Argon / Co2 mix for the Mig. The Co2 allows it to burn a bit hotter and gets better penetration because of this.
