3.3. Ciclo de trabajo
The letter "X" stands for the duty cycle, which is de ned 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 gure.
If transformer is over-heat, the heat relay inside it will open and will output an instruction to circuit
board, cut AC relay and the output welding current, and brighten the over-heat pilot lamp in the front
panel. At this time, the machine should be relaxed for 15 minutes to cool the fan. When operating the
machine again, the welding output current or the duty cycle should be reduced.
