Manufacturer Reviews

Old Man
I am a pipeline welder that made the move to a blue pro 300. Loved it and could not believe they quit making it. We put 9000 plus hours on the 300 and the company I work for replaced it with the big blue 400 pro. I can't believe it but Miller has produced a machine that is better than the 300. I have put 700 plus hours on it and it performs great. I recommend this welder for all types of welding. I wire and stick with this machine and love it.
