Wow you have a lot of variables here. Let's go over some of them.1.AC current 2.100%argon shield gas 3.Check your Tungsten, it must be the recommended 1or 2% and the right size, clean and the tip rounded by meting 4. High freq. turned to continous-not just "START"
5. CLEAN,CLEAN,CLEAN your Alum. with a S.S. brush that has touched NOTHING else in in it's life!
Start here and GOOD luck
