So its not 100% yet but it looks like il be getting a mm200 for free from work. They dont want to invest the time and money in it to fix it. It needs a gun (thinking bernard q300) and il have to get a tank (co2). The main reason im posting is its missing a knob for voltage control iirc and then the big problem of it being stuck on the hottest setting. According to the 2 welders at work (im a hobbiest, mostly fab for my jeep) they tried all different settings all the same. Id love to be able to fix it and i figure for home use itl be great. So to sumarize, is the bernard a good gun choice, knob, and the voltage issue.
