    Manufacturer Reviews

    By: Joseph
    I searched for a few years and watched every review before buying this welder. I opted for the tig runner package with the wireless foot pedal. I can say that it is one of the best investments that I have ever made. There is no job to large or to small for this machine. The Miller Dynasty series welders are simply the best welders on the market.
