3.01 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 with-
out 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.
