What is the duty cycle for the Spectrum 625?

The duty cycle depends on input voltage and output current. At 120V (20A input) with 27A output, the duty cycle is 20%; at 120V (15A input) with 20A output, it is 35%; and at 240V with 40A output, it is 50%. Duty cycle is the percentage of a 10-minute period that the unit can cut at rated load without overheating. The manual provides visual examples of cutting and resting schedules for different duty cycles.
