Hey Brent, looks good. You already know the answer, practice. Ally is kind of a head trip to weld as the magnesium is catching fire and the weld is frying away. The best tip I can give (apart from practice) is to commit to just get in there and get it melting first then get a good rythm going on your feed. Get set up comfortably and use an Amp per thou of thickness. There's more info than you can shake a stick at here
