I am thinking about parting with some Christmas money to buy a welder. I will use it for hobby purposes. 1/2 inch rebar will be the thickest stuff I will be welding. I'm looking at a Lincoln 180 Dual wire welder and a Millermatic 211. Does anyone have any experience or comments on either one of these welders? I have narrowed it down to these two because they can do 110 and 220.
