All I have is gas welders so sadly I would not know.  I actually usually 
use the TIG for stainless, but I recently got wire for the MIG because 
it is faster.  Having to sort out gas blends can be annoying.  I 
generally have pure argon, but I think we mild steel it is not as idea 
(and more expensive)  than some of the blends.

I had not thought of that.  I would be concerned anyway with MIG due to 
the lack of high frequency start to clear the oxides.

Have you used the solid core for mild steel?  How does it work?  I guess 
you have flux you have to chip off like with a stick?
