I could not decide if I needed a 220 volt or wanted a 110 for the convenience. Since I mostly do sheetmetal work or maybe some thicker brackets I liked the portability of the 110. BUT I also have a tractor that needs some welding from time to time so I also wanted a 220 unit with some more power.What I found was A new Millermatic called the 211 with MVP. MVP stands for Multi-voltage plug.It has an end that threads onto the power cord you can plug into a 110 outlet for the small stuff,or a bigger end that also threads onto the cord for the 220 outlet and then you can turn up the power!! I have only used the 110 side so far but it works great and is easy to use.It was $948 and I think it will last me the rest of my life...
