Our millermatic 250 does the same thing. Our millermatic 200 doesn't. I am from the old school that fought computerized welders for a long time, but I like it now. I still use the 200 because it usually has steel wire in it and the 250 usually has a push pull gun with aluminum wire in it, but the computerized features of a 2 yr old welder make welding a lot easier than a 20 year machine.
