I would like to at this time give a shout out to and about Miller welders. Even though my machine was 1 year out of warrenty, without a lot of yelling and screaming, they came thru and repalced all the parts needed to get it back going again. Mind you that this was a DYNASTY 350 ($7000) and it needed about $2100 in parts to get it back running again. I dont know what caused it and from talking to a lot of other people out there, they have never heard of one going off like that. I did have to pay the service fee to the shop that did the repairs ($210) as was fair, But this is an AMERICAN Company that stands wholey behind what they build.
