I use a Lincoln PowerMig 350, and it is a great machine. It has the factory roll around cart, with the dual bottle rack on the back. This is one fine machine. I keep the 2 most common used gases on the cart, and roll it into position. I haven't figured out how to bake cookies with it yet, but it will do so much else, that I can get by without those cookies. The spray transfer and pulse, are great, yet you can do light gauge, in short circuit mode. Don't take one for a "test ride", and unless you are planning on buying. I think it will get your attention.
