Stainless steel welding with a MIG?

[voucht]

Hi,
The DIY stores sell welding wire for MIG for stainless steel welding. I thought you could only weld stainless steel with a TIG, but if the wire does exist, it means that it should be possible with a MIG, no?

I need to weld the stainless steel tubes of my exhaust system, and giving them to a professional welder will cost me a lot of money again.

Shall I try with my MIG, or do you guys absolutely not recommend it? If it is a yes, will my shield gas (Argon + 18% CO2 + 0.03% NO) work for that?

Thank you
