switched off, the lamp will require up to 5 minutes of cooling time before restarting.
G. If the optional drawer type headrest is used, it can be used
as a curing chamber for small parts. To cure parts in the head
rest, pull the drawer open using the black pull knob, and load
components onto the center of the tray (see fig. 8). Close the
drawer, set the power mode switch to the full power position
and wait the appropriate amount of time for curing to complete.
WARNING:
While the drawer is in the fully open
position, the back side of the drawer will block most of
the UV light and prevent it from scattering into the work
area. However, UV glasses and skin protection should
still be worn during curing to insure safe operation.
When curing is complete, set the power mode switch to the
standby position to minimize temperature rise of the lamp head
and headrest. Open the drawer and remove the cured parts.
H. To perform handheld curing, lift the lamp head from the
either drawer or closed type headrest using the handle, switch
to full power mode and hold the lamp 2 to 6 inches from the
target substrate (see fig. 9).
NOTE:
The height of the Lamp can be adjusted up or
down to control the intensity of light reaching the curing
surface. The power setting switch can also be set to the
lower intensity standby mode for more reactive
adhesives or temperature sensitive substrates. Refer to
the adhesive manufacturer’s data sheet for appropriate
exposure time and intensity levels. The optimum height and exposure time required to
provide proper curing may need to be adjusted experimentally.
When curing is complete, place the lamp head back on the headrest, and set the power
mode switch back to the standby position. Note that units with closed type headrests have a
bottom mounted switch that detects headrest insertion and activates lamp standby mode.
6.2 Shut Down
To shut down the light cure system, place the lamp head back on the headrest, and shut off
the input power switch. Allow the lamp and surrounding components time to cool before
placing the head close to temperature sensitive materials or before re-packaging the system
for transportation.
