I am no expert on welders. But a couple of my freinds have burned up Lincolns doing body work. Miller seems to be a very good unit. Mainly because Miller uses a copper transformer,whereas Lincoln uses an alluminum transformer.If I were to buy one I would go to a knowlegable Miller dealer and try to come up with a good deal.I do have a 35 year old Miller stick welder,that has never let me down. It can sit in the cold shop for a couple of years,and when I hit the switch shes ready to go.In all fairness go to a regular dealer who is knowleghable of his product,and go from there.Probably to another dealer.
