[QUOTE="patooyee, post: 468950, member: 483"] I'm still new but I can weld almost anything I need now good enough to be use-able and leak-free. If you're working on aluminum cleanliness is godliness. Not just the area you are going to be directly welding either. The heat will suck oxidation and pollutant in from the edges of the weld and even around a corner on the edge of a plate. You wonder WTF is going on, why can't I get a decent weld. Also not shielding the filler rod with the gas is a big newb mistake that I still make. Pulling the hot tip of the rod out too far will result in an oxidized ball and then when you go to dip again you introduce that oxidation into the puddle. This is frustrating as hell when you have a good clean bead going and then suddenly start getting pollutants. Watching the puddle is key and one of my biggest challenges is keeping it "wet" equally on both pieces. Another thing is that you need to aim the tip of the torch just slightly ahead of your puddle to kind of pre-heat where you are about to go before you get there. The welding beads on beads on flat plate is a good practice exercise. I still go back to doing it when I am trying new materials just to get material-specific practice before I **** up the whole project. I started backwards. I needed to do aluminum right away so I learned on aluminum. I'm still way better on aluminum than steel. [/QUOTE]
