Duty cycle

The EMS 215ic, EMP 215ic and EM 215ic all 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
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.
