As far as the speed, look for the angle of the sparks leaving the cut, try for about 45° . If they are going strait down, you are way too slow. If they are more than 55°, you are close to losing the cut.Need to ask, I am getting a pretty good amount of dross, is this because I am moving to slow or moving to fast, or maybe not enough air pressure, to much air pressure.
