2.08 Duty Cycle

The rated duty cycle of a Welding Power Source, is a statement of the time it may be operated at its rated welding current output
without exceeding the temperature limits of the insulation of the component parts. To explain the 10 minute duty cycle period the
following example is used. Suppose a Welding Power Source is designed to operate at a 20% duty cycle, 100 amperes at 19 volts.
This means that it has been designed and built to provide the rated amperage (100 A) for 2 minutes, i.e. arc welding time, out of
every 10 minute period (20% of 10 minutes is 2 minutes). During the other 8 minutes of the 10 minute period the Welding Power
Source must idle and be allowed to cool.
