I have the miller 140 110v and I love it. It makes me a better welder. I have done everything from sheet metal repair for the body to welding in Subframe Connectors and makes some solid motor mounts. The auto set works great. I measure the thickness and turn the dial, it is that easy. My friend is a pro welder and he always tells how good looking my welds look and I know it is the machine. BTW, I bought mine new for $500
