2.09 Duty Cycle
Duty cycle is the percentage of each ten-minute period of
time that the welding machine may be operated under
rated load conditions. For example, a duty cycle of 60%
means that the machine can be operated at rated load for
an average of 6 minutes of each 10 minute period of
operation. During the remaining 4 minutes, the machine
must idle to permit proper cooling. Figure 3-3 enables
the operator to determine the duty cycle at various welding
amperages.
