Jasic CUT30, Operator'S Manual

8

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.
