  • Aluminum welding problems. Any guesses?

    Hello guys, i recently purchased a millermatic 211 and a spoolmate 100 to do some aluminum welding. I am completely new to welding but have watched hundreds of youtube videos to get me headed in the right direction. Ive been laying down the beads trying to get everything dialed in, and my welds look absolutely terrible! Ive messed with the settings and the gas flow a countless amount of times and can not get anything to look anything like it should! First i thought my issue was dirty aluminum but ive acetoned and wirebrushed(stainless) it and got no better results. Any ideas or suggestions would be greatly appreciated!

    I would upload an image but this forum has major problems with that...
