Hi Greg,
For polishing… 1,100 to 1,300 RPM
For cutting…2,000 to 2,500
For a beginner (which I am) a dual action buffer (aka random orbital) is safer than an orbital. The latter just spins. The former spins, and moves the entire head, resulting in a more random action on paint surface.
Any orbital buffer can burn the paint, regardless of the operating speed. Hence the most important tip, critical on an orbital, but also important on a random… Keep it moving!
A good read for the beginner (and expert for that matter):
I have one of these and really like it. Got a deal on it. One of the SOC guys was selling it, unused, in the box:
