What is the duty cycle of the Millermatic 211 Auto Set on 120V vs 230V power?

On 120VAC, the duty cycle is 20% at 90A, meaning you can weld for 2 minutes then must pause for 8 minutes. On 230VAC at 60Hz, the duty cycle is 30% at 150A, allowing 3 minutes of welding followed by a 7-minute pause. Exceeding the duty cycle can damage the unit and void the warranty. (Page 8)
