hi
i have a 415v single phase welder (6.9kva) and im unsure if i should go for a isolated auto transformer over £400 or a non isolated auto transformer just £175 i have a very good earth system the spike which is chemically earthed is only a few feet from where the welder will be so my question is do i really need to spend all that extra money its a good quality murex welder and using a multi meter the earthing seems really good any comments
to be honest im not 100 percent sure of what the difference is and ho the isolation works or its function but the salesmantold me it was to do with earthing
thanks guys
