Welding for the first time - need advice

Starting to get a little better at it. Not blowing through nearly as often. Seems as if pulling the weld puddle keeps it cooler than pushing it across the gap. Will go back over this to clean up the pin holes. Metal is all warped to hell but I'm concentrating more on just getting decent welds down at this point so I'm not taking a bunch of time to let them cool. Once I feel real comfortable with it, my final practice run on this fender will be the real deal where I cool the welds and do everything exactly the way I'm going to do them on my Duster.
