30+ years ago I purchased a BOC Ltd unit exactly like that, a copper wound tranformer 140 amp AC output, that's probably an Ali wound transformer with about same output.

It looks exactly the same as an old buzz box that I bought from Sureweld over 30 years ago, its still going strong, mine is yellow, and is made by CEA, an Italian company, have a look on the back for a logo.

It's always been called an earth to me,I got told the other name on a welding course.
