5.8 Duty cycle
The EMP 215ic and EM 215ic have 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.
2.5 minutes 7.5 minutes
A different combination of duty cycle and welding current can be selected. Use the graphs
below to determine the correct duty cycle for a given welding current.
