I haven't been on the forum in some time. This last week I acquired a Electro-Graphics Graver, Pat #2.129.999. made in Toledo Ohio.

I'm going to rely on some of the more experienced members of this forum for more info. The unit I have seems to work fine. Anyone know much about this item? Is there anywhere I might find a operators manual? It looks pretty simple but I don't want to burn something out.
There was a sheet in the cover but it is mostly gone and what remains is illegible.
This is not the 'bounce all over vibrating engraver' that is common today. This uses an electric arc.

If one needed to replace the actual point that makes the engraving what would work? Tungsten rod of the correct diameter?

Thanks...Gil
