Relationship with ratedload
Rated duty cycle refers to the percentage of the normal work time of the machine under rated
maximum current holding in the period when taking 10 minutes as a period. The rated duty cycle
of this machine is 40 -60%
.
Using the cutting machine continuously overrunning the rated load
may lead to overheating of the machine, and frequently using the machine overrunning the rated
load may accelerate the aging of the machine or even burn the machine.
