I have 2 Millers 251's and a Lincoln 180 WeldPac in my shop and dollar for dollar the Lincoln is the best for the buck!...........But remember it's limits, multiple passes have to be made in thicker material,it is great for hard to get at tight places compared to the Millers larger gun,but also comes with a shorter 10ft,so be perpared to buy a good quality 220 volt extension cord. Also the 220 volt model is the only way to go, much more steadier with constant power. And If i might add, if you only use this welder occasionly,install a wire wipe system between the the wire and the feed rollers, to insure the wire is only fed clean wire,(cheap to buy @ about $10.00).
