3.2 Duty cycle and Over-heat
The letter “X” stands for the duty cycle, which is defined as the proportion of the time that a
machine can work continuously within a certain time (10 minutes). The rated duty cycle means
the proportion of the time that a machine can work continuously within 10 minutes when it
outputs the rated welding current.
The relation between the duty cycle “X” and the output welding current “I” is shown as the
right figure.
