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 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, 200 amperes at 18 volts. This means that it has been designed and built to provide
the rated amperage (200A) 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.
