§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 to cool the fan. When operating the machine again, the welding output
current or the duty cycle should be reduced.
