Hi Rita, I have a Bobcat that has a marver attached to it. So yes, you can do it if you want it.
I also run mine on an oxycon, but I'm not sure at the moment what it is - I'd have to look and right now I'm too tired to get up. LOL! I will post again in the morning. I'm not sure where it came from originally, as I bought all of my equipment from someone who was giving up the craft.
