Hopefully, not too much of a hi- jack....if so, please disregard.
I have also done the mig to tack, then tig to fill in with good results. As Greg said the ability to more easily grind the tig filler and hammer and dolly it helps a ton. I'm very far from great at this BTW, but I try.
Has anyone used "ez grind" mig wire before? I haven't, but am curious about it. It supposedly has properties closer to the tig weld for grinding and hammer and dolly work.
Oh and fit up, fit up, fit up is huge........i struggle sometimes to pitch a patch in the trash, but if it isn't right......do it and make one that fits right. You will be better off in the end.
