Thinking about getting a welder

Buy something you can get parts for. It sucks when you fry your tip or waste your feed cable liner in the middle of a project and have to order repair parts.
I am having problems with my Miller 185 feeding wire, Probably the liner. My Miller Vintage at work never has this problem. My 220 units do not dial down to do sheet metal very well like the 110 units do but do way better on anything thicker than 1/8". Buy the one you need.
