when I looked at the Eastwood’s they had a low rating and were OEM’d through either a chinese or italian company. If I remember right it was the same one campbell-hausfield used.
I ended up with a well used Century welder, but I looked for a year for one that was cheap, and had untapped controls and ran on 120, and it does aluminum if you buy the spool gun. (although there is a way around that.) However, because Lincoln bought Century, I can get parts and they sent me the manuals and charts for it. There are some deals out there, but I would stick with the big guys.
