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:
Good ventilation
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 30cm.
Over voltage is forbidden
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.
Overload is forbidden
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.
Suddenly the "E60" code may appear on the digital screen 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.
Replacing the components can be dangerous.
Only professionals can replace the components of the machine.
Make sure there are no foreign bodies such as wire leads, screws, gaskets and metal
bars falling into the machine inside when replacing the components.
Make sure the connecting wires inside the machine are correctly connected after
