Hi Ken - Sorry I missed your post earlier. Because the slices are so thin, and I am assuming already cooked/ready to heat and eat, you could get a good smoke going and then place the meat in the smoker, lock it down and shut off the electric after a minute or so. The residual smoke and heat would probably be enough. Leaving the smoker element on could dry out the ham. Adding a small tray of water when you fire up the smoker initially my be good to help keep the meat moist.
