1.4 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 40% duty
cycle, 40 amperes at 96 volts. This means that it has been designed and built to provide
the rated amperage (40A) for 4 minutes, i.e. arc welding time, out of every 10 minute
period (40% of 10 minutes is 4 minutes). During the other 6 minutes of the 10 minute period
the Welding Power Source must idle and be allowed to cool.
