I forgot to ask a question before. Again, I have a silver puppy. I'd bought some silver rods for in the future. The rods that came witht he silver puppy have another kind of little metal collar that is on the end of the rod that plugs in to the generator but the new rods don't; they are just silver. Can I use the plain silver rods in this generator or does it need this other metal collar to keep the generator running?

Thanks again, (Thank goodenss all of you are here as I am a bundle of questions and want to get this right).
