2.4 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,
185 amperes at 23 volts. This means that it has been designed and built to provide the
rated amperage (185A) 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.
