Safety and monitoring devices
EMERGENCY STOP devices
The device is equipped with the following
EMERGENCY STOP facility:
•
EMERGENCY STOP button on the left exterior
of the device:
This button disconnects the laser power supply
from the mains. The heat exchanger and cont-
rol remain on.
Note: Take note of the discharge time of the
capacitor bank!
Protective coverings
Each time before turning on the machine, all covers
must be properly mounted.
Safety switch
Each time before the machine is turned on, the
safety switches (interlock switches) of the working
chamber door must be checked for proper operation
(

The safety switches may not be removed or bridged.
The danger otherwise exists that an uncontrolled
laser beam will cause serious eye damage or skin
burns.
Personal protective equipment
While properly using the machine, the eyes are
protected against damaging effects of the laser
beam and against the UV radiation arising in the
welding plasma and hazardous to the eyes while
