Control Panel
A. Temperature Gauges—These show the temperature of
the laser's power supply and cooling water system in
degrees Celsius (±3°C). Do not allow either reading to
exceed 38°C.
B. Ammeter—This shows the amount of current being used
by the laser tube.
C. Emergency Stop—This button immediately cuts all
power to the laser in the event of an emergency.
D. Laser Power Display—This displays the current power
of the laser as a percentage of its maximum intensity.
Adjust this setting accordingly to process various materi-
als. For most materials, an intensity between 20% and
60% is optimal. When aligning the laser beam, you
should use a setting around 11% for safety reasons.
E. 10/1/0.1—These buttons are used to adjust the laser's
power in increments of 10%, 1%, and 0.1% respectively.
As expected, + increases the power by the matching
increment and − decreases the power by the matching
decrement. Again, running your laser tube above 70%
power can significantly shorten its service life.
F. Laser ON/OFF—This switch controls the power to the
laser tube. Turn it on after and turn it off before the main
power switch.
G. Laser Test Button—This button fires the laser manually.
H. Indicator—This light shines when the laser is active.
I. ON/OFF—This is the main power switch. When
switched to ON, the laser head should move to the top left
corner of the main bay.
Internal Wiring
A. Temperature Sensor—This sensor provides the reading
for your control panel's "Power" temperature display.
B. Laser Power Supply—This device transforms standard
electricity into the extremely high voltage charge necessary
for the laser tube.
C. Terminals—These terminal blocks hold your wiring in
place for easier part replacement when needed.
D. Motherboard—This circult board controls the engraving
process, responding to commands from your engraving
software or the machine's control panel.
