Very large oil cooled arc welder, can be used by 2 operators up to 300amps or single operator up to 600amps. Did work last time I used it 12 months ago but really it needs a good service or restoration. Quite a rare beast now I just have far too many projects and too little time to be able to restore this as well so looking for a new home. This is very heavy so able to load with forklift . It does roll on the wheels but it’s not easy, comes with the welding leads in the photos
