That old copper wound unit of yours is probably a pretty good dependable unit even though it will use a little more power. The kind of stuff I do, those small ones just won't do the job. It all comes down to what you are going to be welding. I have always been of the opinion it is better to go with a little larger unit than you think you will need.
