I have a Lincoln mig welder and I'm wanting to modify my Magnaflow exhaust. I want to cut the converters out of the exhaust and put in a piece of pipe. The pipe I want to use is 16 gauge mild steel. Can I weld the mild steel to stainless without any trouble with my Mig welder. I only have flux core wire now, I know this is not the best stuff but I haven't gotten any gas for the solid wire yet. Will this work on the stainless to mild steel weld. I don't really care about the looks of the welds, I just want it to hold on the exhaust.
