What is the duty cycle of the Dynasty 280 at 280 amperes in stick (SMAW) mode with three-phase input?

At 280 amperes with three-phase input, the Dynasty 280 has a duty cycle of 15% for stick (SMAW) welding. This means the unit can weld for approximately 1.5 minutes out of every 10-minute period at that output. Exceeding the duty cycle can damage the machine or torch and will void the warranty.
