dont move so quickly and maybe try whipping the leed back and forth a little bit (kinda like the "c" pattern people always talk about) also your voltage may be a bit to low. It looks like the weld is not burning in real deep. also its hard to put down a nice bead on a flat surface like that, especially when its on the side of your framerail. the welds you put down will work just fine for filling a few gouges in the frame
