Hello, I am currently the owner of a Rowac/Venvulas Mig machine. This is based on the older, non digital Sparom 905 by Lorch. I would really like a manual, so I can setup the machine better then it is now. Howver, as it's not an official Lorch machine I can not download the manual from the Lorch site, as my serial number is not recognised. Can anyone with an older Saprom 905 download the manual from Lorch and send it to me please? Lorch dealer/importer in Holland does not want to help, Rowac did not reply at all.
