Hey everyone I'm new to the world of electrology ,but I'm completely fascinated by the whole thing. I have a kree imperial electrolysis aperatus how ever it seems as if something is missing I was wondering if anyone could give me some more insight on this " model 200" it has the obvious 110v plug. a foot peddle with corresponding port/input and a "needle cord" port it's red. however there is no sponge cord or other input or port and maybe I'm wrong but I think there's supposed to be a negative and positive.
