Duty cycle

5.5.1 25% duty cycle
The Rebel EMP 205ic AC/DC has a welding current output of 205 A at 25% duty cycle
(230 V). A self-resetting thermostat will protect the power source if the duty cycle is
exceeded.
Example: If the power source operates at a 25% duty cycle, it will provide the rated
amperage for a maximum of 2.5 minutes out of every 10-minute period. The remaining time,
7.5 minutes, the power source must be allowed to cool down.
