Nothing in particular yet just getting familiar with the machine. I'm only in from school for the weekend so I dont have much time to get use to it but I did get to lay a few beads down. Arc is really smooth on steel and I did a little bit of aluminum but for some reason my tungsten is balling up and burning away. Its 3/32 2% Lanthanated at about 140max amps on 1/8" Aluminum. I dont know if thats to much for the 3/32 or not. But i do have a cold air intake I will be making and I need to weld on MAF flanges
