Very good advice on going to a good weding shop.The Lincolns seems to be Ok if your just gonna use them occasionally,for light work.A couple of my freinds have burned up their Lincolns just doing body work.Reason is Lincoln uses an alluminum transformer whereas Miller uses a copper one.If I was buying one I would invest the extra $$$s and buy the Miller.My only welder is an old Miller AC 220V stick welder,which I have had for about 35 yrs.It still operates as good as new.I have looked at the Mig welders but decided I didnt really need one.
