One look at this welder, the size of the wire spool, 600 volt cord, MIG torch and 300 amp electrode holder is enough to tell you that this is a serious welder . I have used Miller MiG welders, owned a Hobart and used many others but this is a lot more power for less money. AMAZING VALUE! Now I understand why a professional welder bought three of these. THIS IS THE REAL DEAL!
