Been talking about upgrading to a 255, has some nice features, like the quick disconnect and portable size, inverter machine and more energy efficient with higher capacity. Local welding supply said 4200 for a new 252 and 4800 for the 255… not sure why they are so close. In any event the 252 is I believe a 2010 model year, cart, regulators, miller gun and drive rolls for .030 and 0.035. I know there have been some folks on here looking at used welders and probably have a better idea on what to start asking for this one, I’ll post a picture later it is in nice shape, some paint scuffs on top but otherwise excellent.
