Duty cycle is the key factor to consider when selecting a power source. Once the engineer has determined the current and voltage needed to accomplish the weld, he then reviews duty cycle requirements.Duty cycle rating is the percentage of time during a 10-minute period a power supply can operate at rated output amperage without overheating. A 300 A machine at 60-percent-duty cycle can weld for six minutes at 300. A during a 10-minute period. Alter six minutes, the welder must rest the machine for the next four minutes to avoid overheating the unit.
