Omtech USB3020B User Manual page 8

Main Parts
A. Cover—The cover provides access to the main bay for placing and retrieving materials, as well as fixing the laser
path alignment and other maintenance. Power to the laser is automatically cut when the cover is opened.
B. Viewing Window—This acrylic window allows you to monitor the engraving process but only partially absorbs
the high infrared laser and is NOT otherwise protected against it. Always use protective eyewear when observing
the active laser and never stare at it for extended periods.
C. Warnings—These notices supplement the Safety Information chapter of this manual. Read them carefully before
using the machine and contact our customer service or tech support teams if you have any questions or concerns.
D. Temperature Gauges—These monitor the temperature of your laser power source and the tube's cooling water in
degrees Celsius (±3°C). Do not allow either reading to exceed 38°C. If the temperatures approach this value, stop
work and allow your device to cool before further use.
E. Ammeter—This shows the amount of current being used by the laser tube.
F. Emergency Stop—This button immediately cuts all power to the laser tube in the event of an emergency.
G. Control Panel—The control panel offers hands-on control of your laser's intensity and includes a manual trigger
for testing and troubleshooting.
H. Caster Wheels—The front wheels include locks to hold the engraver in place.
I. USB Port—This connects to your control computer and its engraving software.
J. Vent—This vent helps keep your engraver's electrical components from overheating. Do not block it with any
objects and remove any dust that might accumulate.
K. Rear Access Door—This door opens to the laser bay, holding the laser tube and its connections.
L. Laser Tube—This CO₂-filled glass tube is mounted on brackets and immobile. Its connection to the laser power
supply is extremely high voltage and extremely dangerous.
M. Water Sensor—This device provides the reading for the control panel's water temperature gauge.
N. Power Socket—This socket connects to your main power supply. Be sure that the supply is stable and matches the
voltage on the label above the socket.
O. Ground Connection—This socket must be connected to a safe electrical ground (see §3.6) if your location does
not have a well-grounded 3-prong outlet.
P. Connection Sockets—These sockets connect to your water pump if needed and air assist if a different laser head
with an air assist outlet is installed. It is recommended, however, to use a separate plug on a different fuse for these
devices.
Q. Exhaust Fan—This fan pulls out gases and airborne debris from the worktable, sending it through your vent to a
window or air purifier.
R. Water Tubes—The blue line brings cooling water from your pump or chiller to keep your laser tube cool and stable
and the other line returns it.
