i am having a discussion with a friend about the mm250, i did own one recently, sold it to buy a tig, i have had and still use a mm200, i know very little about the 250, the one that i had had volt and amp/ipm gauges, it was a digital readout, my question. has the mm250 always had the digital gauges, i am thinking that it did when miller upgraded from the mm200. but i am not sure, any one know, much appreciate any input
