I DO like the idea of having 110 as well as 220. I do not have that. Mine is all 220. Its restrictive because I cant just take my welder to a friends shop. But then again, they wouldnt have the Argon/CO2 bottle and its not easy just hauling this stuff around. Nonetheless I would love to have the option.
The other thing I see in my future is a TIG. Maybe I am watching too many TV Resto Shows? Looks intriguing!
