yes I have done alot of research on here and pirate, but has anyone actually have a weld fail due to welding mild steel to the housing?? I have always heard to pre-heat and use nickle rod but I have also heard of lots of people just pre-heating and using flux core in a mig. I have also "heard" of the cast breaking off around the weld because it made it brittle. I need to weld some tabs to my 14b housing to run a limiting strap, all I really have access to is a mig. Real world experience??
