You can see by the center picture that the base metal actually fused together, the first one, you still see a gap in the 2 pieces of metal. The 3rd shows they almost burnt thru the base metal. Thanks for the photo's Tucker..

The back side penatration is ok for thin stuff, anything thicker than ,say .25" should be prepped fiesta and back welded then fillets welded on the face. That is later as you become a certified pro, for now, keep doing what your doing and practice some vertical. Try not to do spot type vertical with a MIG, as it is not a recommended procedure and will not allow for good penetration, you need that deposition puddle to meld the metals together .
