GENERAL
DUAL PRO 14W LASER HEAD OVERVIEW
The new Dual Pro 14W laser head is the optical combination of two 7W PRO laser diodes. They are combined and
then the beam is collimated and compressed into a square, increasing the power density and making the beam
equal in both axis.
The magnetic shroud allows for easy mounting of the laser head to multiple platforms and also provides a safety
viewing window for the laser processing. The focus lens of the laser has a fixed focus at ¼” below the shroud.
Lifetime of the laser at the recommended 3amp setting is 5,000 to 10,000 hours depending on the environmental
conditions.

UNPACKING
Inspect the shipping container for damage.
Verify the contents of the package:
•Dual Pro 14W Laser Head
•Focus Tool
•OD4+ Safety Goggles with Case
OPERATION
LASER FOCUS
The laser is fixed focus to ¼” below the laser shroud. For engraving, you can focus the laser to the top surface of
the material using the focusing tool provided. For cutting, we recommend putting the focus at the bottom of the
material. For example, if you are cutting 1/8” material, then set the focus of the laser at 1/8”. If you are cutting ¼”
material or more, then put the laser almost touching the material to allow for the focus to be at the bottom.

BEAM PROFILE
The 14W Dual Pro laser uses proprietary technology inside the laser diode package to decrease the total beam size
while increasing the total power. This makes it the smallest spot size possible in a diode laser.
The energy from the sides of the rectangle are superimposed into the center, increasing the power density,
reducing the spot size, and making the beam uniform.
Spot size on wood typical is about 0.006″ or less. On Acrylic, it is 0.0045″. On tile it is 0.0035″.
OUTPUT CONDITIONS
The laser diode output will vary depending on the temperature. Warmer temperature environments will reduce
the power of the laser. Do not have the laser in under 0 degrees C. The laser diode will also require more current
to maintain the same amount of output power as the diode degrades.
NORMAL OPERATING CONDITIONS:
The laser diode will operate at its optimal level for thermal performance at 3 amps. Additional current above this
level will lead to possible degradation of the laser output and thermal damage if additional precautions for thermal
management are not taken. It is possible to reduce the current on the diode to increase the lifetime of the laser.
Running at higher current levels reduce the lifetime of the laser.
STATIC PRECAUTIONS
Take precaution when handling laser diodes as they are a static sensitive devices. Static electricity and electrical
surges will degrade the performance of the laser diode.

LASER SAFETY
Laser light can cause damage to eyesight and skin if proper laser safety is not used. Always wear the appropriate
laser goggles to prevent any laser light, either directly or indirectly to contact the eye. Never expose skin directly
to laser radiation. Focused light will increase the safety hazard.
CLEANING THE LENS:
Sometimes soot or smoke can get onto the lens surface when processing, causing decreased levels in output
power. This is especially needed for cutting projects. If your lens is dirty, then it will significantly reduce the power
level.
To clean it, use a q tip and isopropyl alcohol. Dip the q tip in alcohol and then put it up into the lens holder and
give it a twist or two to remove any debris. Take the q tip out and let it dry for 5 minutes before use.
LASER CONNECTION
If your laser was part of a driver kit, it will be cabled with a Molex mini fit Jr connector which will connect directly
to the laser driver board output.
•Connect the laser to the Molex Mini Fit Jr. Header "H3" for laser output on the Dual Pro Driver Board.
MOUNTING
The laser has several magnetic mounting kits available. Check the product website under the magnetic mounting
kit section to see one for your machine or use the generic magnet mount.
The magnet mount makes it easy to remove the laser when using the router to carve. Simply disconnect the wires
from the gantry connections and remove the laser from the mount. When you want to use the laser, then re-
connect the wires and place the laser on the mount.
