Min PWM Factor
The Minimum Pulse Width Modulation (PWM) Factor is a factorial value used to maintain firing power when
cutting a sharp contour in metal. The laser power is directly proportional to the speed in which the cutting head is
moving, and the laser will naturally reduce power prior to a sharp contour. The Min. PWM Factor instructs the
laser not to reduce power to 0 but to limit the minimum output power when cutting metals since most metals
cannot be cut at a lower laser power.
