working on finishing up 3" stainless steel exhaust. its is tack welded with a mig ( passport plus ) using .035 308 wire and stain mix gas. been practicing on scrap pieces but it seems like i'm going to need to get it tig welded,
so my question has anyone accomplished a good looking weld with mig and if so please share ,settings, process ,pics
. I will be grinding down weld for esthetics but trying to minimize as much as possible. I'm sure I will need to purge if I decide to tackle this if its possible. .
stain mix has a lot splatter should I be using cO2 or other shielding gas.
