This is my second welder from Miller. I had a 185 Autoset a few years back and now this 190. It's tiny and light weight footprint makes it perfect for my Jeep building hobby and the fact that it can do up to 5/16th mild steel is perfect. I doubt I will ever weld anything bigger than 1/4" but it's nice to know it can be done. For the money you can't beat it and nothing surpasses the quality of a Millermatic product.
