§3.2 Duty cycle & Over heat
The letter “X” stands for 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.
If the welder is over-heat, the IGBT over-heat
protection unit inside it will output an instruction to cut
output welding current, and brighten the over-heat pilot
lamp on the front panel. At this time, the machine should be relaxed for 10 minutes to cool the fan.
When operating the machine again, the welding output current or the duty cycle should be reduced
