I'm going out on a limb and thinking that you've never polished with a PC before. If so, some polishes do dry out and create dust when your polishing. Some are worse than others. The poorboy's SSR series creates alot of dust while polishes like those made by Optimum create very little to no dust at all. Don't be alarmed when your polishes start to dust up, its perfectly normal. You can use the dusting as a sign that you need to add more polish to the pad soon.
