TION AND CONNECTION
Overcurrent/overvoltage/overheating protection circuit is installed in this machine. When the mains
voltage, output current or inner temperature exceeds the set standard, the machine will stop
automatically. However, excessive use (e.g. too high voltage) of machine may also damage the
machine, so please note:
This cutting machine can create powerful cutting current and has strict cooling requirements that
cannot be met with natural ventilation. Therefore the built-in fan is very important in enabling the
machine to work stable with effective cooling. The operator should make sure that the louvers be
uncovered and unblocked. The minimum distance between the machine and nearby objects
should be 25cm.
This machine is of automatic mains voltage compensation, which ensures that the cutting current
varies within the given range. In case that the input mains voltage exceeds the tolerance value,
it would possibly damage the machine. The operator should understand this circumstance fully
and adopt relevant precautions.
Remember to observe the max load current at any moment (refer to the corresponding duty
cycle). Make sure that the cutting current should not exceed the maximum load current. Overload
could obviously shorten the machine's lifespan, or even damage the machine.
A sudden halt may occur with the yellow LED on the front panel on while the machine is of
over-load status. Under this circumstance, it is unnecessary to restart the machine. Keep the
built-in fan working to lower the temperature inside the machine. Cutting can be continued after
the inner temperature falls into the standard range and the yellow LED is off.
