3.2 Duty cycle & Over heating
The letter “X” stands for duty cycle, which is defined as the
proportion of the time that a machine can work continuous-
ly 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 overheats, the IGBT over-heat protection unit
inside it will output an instruction to cut the output welding
current, and will light up the over-heat pilot lamp on the
front panel. In the even this occurs, 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.
