Well here is my opinion, I welded for 40+ years I think that the down hand weld is not as strong as vert up but a lot of shops that do roolbar work use it. thay are putting a 20" gas line in down the street from me, welded down hand, E7010 just like we welded it back in the 60 . And to me mig welding is junk weld I have seen some of them atculy peel off By the way the cage in my car is miged vert up
