This is a mig welder. This is Lincoln's answer to the "millermatic". It is a wire feeder and power source together. Never welded with one, but knew a paving company with one. I would say it is old and heavy, but I am sure it will weld nice. Keep in mind that older machines can have limited parts availability, or expensive parts(not economically feasible). Bigger industrial welders have the power source and feeder separate. Oh, and this is a constant voltage welder so it will not stick weld. You will need a constant current machine or cc to stick weld. Good luck.
