I'll jump in, too. I use mild steel wire with CO2, and it welds all the
300
and 400 series stainless I can lay my hands on. You do (as said before
here) lose the stainless quality not only at the weld, but in a region
around it. But that's not so tough, if you've got a piece of merchant
stock
welded to it. (that's usually what the "MS" after an alloy means, not
"mild
steel")

Wow!! 400 series, too? Any problems with cracking? The 400 series is
heat treatable. Can't help but wonder what's happening when you weld on it.
