Yup. For the 1hp I have to suit up with my leather welding coat, gloves, safety glasses, and face shield. And you really have to be mindful of stance and how you hold the piece to the wheel. If it takes the piece from you let it go. It pulls the piece down and back. I have a rubber stall mat under it so nothing ricochets off the concrete floor. So far I haven't had a wire wheel throw anything at me but little wire darts.
