Hello everyone sorry to bother you with my lack of skills but I need help . I have a millermatic 140 with a 100 series spoolgun. I am using 100% argon and I can not get a good weld on aluminum. I am watching the mig videos and the wire never reaches the metal but all I get is a ball building up and clogging my tips. I did manage a couple good welds but it nothing like the videos I get droplets that slowly build up and drop onto the aluminum. I have the machine setup to 60-70 for wire speed and 2-3 for power. anything higher and all i get is alot of smoke and no sticking at all. I am sorry if I dont make much sense but maybe someone can help me..... THANKS
