Only the positive electrode will yield or precipitate its metal so if it's bare 
copper then you will get the copper mixture and the other metals that are mixed 
in that copper mixture 
Bear in mind that copper doesn't yield so easily in this manner, it may be that 
some of the more unwanted stuff leaches out first
I would say if you're going to use a Godzilla type device, to make sure that 
the positive electrode is not toxic, so maybe use a small 2-3 inch silver wire 
in the end and wrap it up and then place that near the affected area
It is for these reasons that for skin use I use tens machine pads.
I have found that myself and others have benefitted from beck type devices.
I haven't used a Godzilla type device but I am on the microelectrocity yahoo 
forum and the feedback seems decidedly positive to the point that I would 
definitely try it out sometime.
To the point where it's simple and cheap construction and easy and safe 
application and reportedly quick results means that the beck/rife/Clark devices 
aren't even mentioned anymore!
Food For thought!
Peace to all!
