25. Ensure that all personnel in the area are wearing protective eye-wear.
26. Assure the red self-adhesive aperture seal s removed.
27. Place a power meter, or appropriate beam block, 61 cm (24 in) from the laser aperture to prevent the
beam from traveling beyond the work area.
28. Connect the Quick Start Plug to the User I/O connector on the rear of the laser and then connect the
PWM signal source) to the BNC connector on the Quick Start Plug.
Note: Before performing the initial start-up sequence, you must first connect the Quick Start Plug or you must
provide the required Remote Interlock and Shutter Open Request signals to the User I/O connector. See
User I/O connections in the Technical Reference chapter for interface details and signal descriptions.
Warning
Serious
personal
injury
External tickle use may cause laser to fire!
Failing to set the chiller above the dew point of the room, by at least two degrees, can
create a condensing environment inside your laser that could void your warranty.
Do not ow coolant through the laser for an extended period of time when the
laser is shutdown.
This causes condensation to form inside the laser which may result in catastrophic
damage to internal optics and electronic circuits.
Caution

29. Assure the chiller is not set above the room’s dew point. First, measure the temperature and relative hu-
midity in the area you plan on using your laser. Once you have that data, use the Dew Point table,
located in the laser’s Operation Manual- technical references chapter, to determine your dew point.
If you nd that the dew point temperature, is below your chiller. Do not operate your laser without
adjusting the chiller so that it is above the dew point by at least two degrees, use gas purge, and air
conditioning the room.
Start purge gas ow at a rate of 0.85–1.7 m
3
/hr (30–60 SCFH, Standard Cubic Feet per Hour) at a pressure not
to exceed 34.5 kPa (5 PSI). If a ow-meter is not available, set a purge pressure between 13.8–34.5 kPa (2–5
PSI). Air conditioning the room will also help.
30. Make note of the current PWM setting. Set the PWM signal source to provide zero percent output
(0.0%).
In dirty or dusty environments; however, it ma be necessary to purge the laser continuously to prevent
contamination of internal optics. As always, if your Pulstar p100/150 laser fails to lase, refer to Trouble-
shooting in the Maintenance/Troubleshooting chapter for troubleshooting information.
Initial Laser startup:
Before your laser is put into service for the rst time, follow this procedure to verify the laser system is oper-
ating at optimum performance.
