INSTALLATION
2
2.1 General
The PortaRay light cure system may be placed on any bench or shelf that has access to an
120VAC or 240VAC 50/60-cycle single-phase power source in a clean operation area.
CAUTION: Unless otherwise specified at time of order, the system ships with the
default configuration of 100/120VAC ±10%. To order systems configured for
200/240VAC ±10%, contact the factory or your
Uvitron representative (refer to Configurations table
in Specifications section for part numbers). The
unit’s voltage configuration is clearly identified by a
bright orange label and also on the serial number
label, both at the side of the lamp head. Operating
with voltage outside the specified range may result
in damage to the system.
Since the PortaRay is an air-cooled unit, dust or airborne
particles can clog the internal cooling passages and cause
overheating. Allow a 6-inch clearance on all sides of the
lamp head for unrestricted clean airflow.
2.2 Mounting
The lamp head assembly should always be placed on the headrest, or held away from any
flammable surfaces. Never place the lamp head directly on the work surface. The PortaRay is
also designed to be fixture, machine or conveyor mounted using the threaded holes in the top
or bottom surface of the lamp head (see fig. 2 below).

INSTALLATION (CONTINUED)
2
The lamp head assembly can also be placed on a shelf type structure, supporting the unit by
its bottom outside edges. For this type of mounting, a windowed hole must be cut in the shelf,
which would provide adequate clearance for the unit’s bottom-side light exposure opening,
and also for the cooling air exhaust holes.
2.3 Shielding
All installations should incorporate adequate shielding of radiated UV light, in order to prevent
eye and skin burn of the operator or others passing through the work area (refer to UV Safety
Warning in the following Safety Considerations section of the manual). The supplied UV1428
closed headrest or UV0539 headrest / curing chamber can be used with the PortaRay to
minimize the amount of stray UV light scattering in the work area. Custom shielding may be
constructed using sheet metal, welding curtains, UV blocking acrylic or polycarbonate to
prevent operator exposure to UV radiation.
WARNING: To prevent risk of eye or skin burn, all personnel must be protected from
direct or indirect exposure to the UV light produced by the PortaRay curing system.
Extreme care should be used when designing custom UV shielding to insure
personnel will not be exposed to harmful UV radiation. Additionally, UV protective
glasses and protective clothing should be used at all times while working in the vicinity
of the UV curing system.

SAFETY CONSIDERATIONS
3
3.1 UV Safety Warning
Ultraviolet radiation can cause severe burns to eyes and skin. Do not look at
the light without protective eye shielding. (UVITRON UV safety glasses P/N.
UV0496, UV2232 or equivalent)
While thermal burns are felt immediately, UV burns are not felt
for several hours. Short exposure to UV lamp radiation can
cause severe burning of skin and eyes. UV burn of eyes
affects the cornea and burning takes several days to heal. UV
burn is identical to “Welders Burn” and will feel like sand in the
eyes that cannot be washed out. The discomfort is temporary
and has no lasting effects. Some effects of UV radiation can
cause permanent damage to the eyes. Never look directly at
the operating arc lamp, with or without UV protective glasses.
Exposure to UV radiation of only limited time will cause
erythema (redness) on normal skin. Remember that a few
seconds of exposure to direct radiation of the lamp can cause
burns equal to a day in the sun. Such redness is temporary
and will not produce blistering, or tanning, as only a small
amount of radiation penetrates deeply. Extended exposure to
UV radiation can lead to skin cancer. When in the immediate
vicinity of an operating UV emitting arc lamp, the use of UV/IR
protective glasses, protective clothing and cotton gloves is
required.
3.2 Electrical Safety
High voltage and current energize the UV Lamp. A high voltage power supply
and igniter combination is designed to provide lamp-starting voltages, to limit
current, and subsequently provide a uniform output of energy. To avoid the risk
of electrical shock, do not attempt to replace the lamp before turning off the
power input switch, and disconnecting the input power cord.
High voltages are also present inside the PortaRay lamp housing. To avoid to the risk of
electrical shock, no attempt should be made to disassemble the unit or to otherwise access
the circuitry, wiring or other internal components of the PortaRay lamp system. The electrical
system of this unit should be serviced by only UVITRON service personnel.

SAFETY CONSIDERATIONS (CONTINUED)

3.3 High Temperatures
Due to the high output power of this system, high temperatures may be
present on the surfaces of the lamp, reflector, lamp head and headrest.
Extreme care should be taken to prevent touching any of these surfaces
before allowing sufficient time for all temperatures to drop to safely back to
room temperature after power has been removed. Also, the lamp head assembly should
never be placed on or near any flammable surface while the lamp is on, or before its
temperature has cooled back to room temperature. Never place the lamp head or parts to be
cured on a heat sensitive surface. Always cure parts on a metallic or non-flammable surface.
When the unit is not in use (or idling), place the lamp head on the headrest, and switch the
top mounted power level switch to the low power standby position to minimize temperature
rise.
WARNING: Placing the Lamp Housing Assembly on or near flammable surfaces while the
lamp is on, or still hot could result in fire.
3.4 Ozone Safety
High concentrations of ozone (O3) can cause discomfort, or at sufficiently
high levels can be dangerous. Arc lamps that are used in light curing
systems may generate ozone when oxygen in the air is exposed to short
wavelengths of light produced by the lamp (<210 nm). This ozone generation
can be avoided by using arc lamps that are constructed with ozone-free
quartz glass, which absorbs the ozone producing wavelengths. This type of
glass is used in Uvitron’s UVA and visible type lamps. Unfortunately, this ozone-free glass
also can reduce the effectiveness of some curing processes that may require the absorbed
short wavelengths (e.g. those for some inks and coatings). For this reason, Uvitron’s UVB
type lamps are not constructed with ozone-free glass, and should be used only in well
ventilated work areas. Another way to cope with the ozone is to exhaust the lamp air
outdoors. Such exhausting involves no danger as the hot ozone containing gas is very
unstable and breaks down to oxygen rapidly in ducting.
Although some PortaRay system configurations generate ozone at a level that could barely
be detected by odor and at a level well below the 0.1 parts per million allowable limit for
continuous exposure (American Conference of Government Hygienists), it is recommended
that all PortaRay lamp systems be operated in well ventilated areas. For U.S. government
recommended ozone exposure limits and additional ozone safety information, visit the
following OSHA web page:
https://www.osha.gov/dts/chemicalsampling/data/CH_259300.html

3.5 LAMP RECYCLING
UV curing arc lamps (sometimes referred to as bulbs) all contain some level of
mercury, and should be disposed of responsibly in accordance to local, state
and federal laws. Excellent guidelines for mercury lamp recycling can be
obtained at the following National Electrical Manufacturers Association website:
www.lamprecycle.org
Or call Uvitron customer service at (413) 731-7835 for more information.

THEORY OF OPERATION
4
4.1 Light Curing
Ultraviolet Light (UV) exists around us as one of nature's
phenomenon, an example of which is Ultraviolet (UV) rays
produced by natural sunlight. Ultraviolet can also be artificially
produced by an electrical arc lamp enclosed in special glass to
allow it passage (a UV arc lamp).
Reactive materials called photoinitiators are added to resins for
adhesive bonding, coating, sealing, and printing. Ultraviolet
light will cure these adhesives by causing the liquid resin to
polymerize, thus becoming a solid. This could be compared to
two part epoxies, which when mixed in the proper proportions,
turn from a liquid to a solid. Light curing resins, on the other hand, are single component
products ready to use as received without measuring or mixing, and cure on-demand when
exposed to UV light.
The photoinitiators added to the adhesive chemistry react to a specific range of light
wavelengths, and the speed of the reaction is governed primarily by the intensity (or
irradiance) of the light source for those wavelengths and by the chemistry of the adhesive.
Approximate adhesive cure time can be calculated as follows:
Curing Time [seconds] = Light Energy [Joules/cm2] / Light Intensity [Watts/cm2]
Adhesive manufactures typically specify the energy required for curing, or the required
intensity and time duration. For some adhesive types, the relationship between the speed of
curing and lamp intensity is not linear (doubling the intensity does not offer half the cure
time). The fastest and most complete reaction may occur at high peak intensity for a relatively
short period of time. This may be a more effective type of curing as compared to a similar (or
even a higher) dose of UV light, which is spread over longer period of time.
NOTE: Various types of inks, coatings and adhesives from different manufacturers
have different levels of reactivity which will require adjusting of exposure times for
proper curing. Consult with the adhesive manufacturer for appropriate cure times for
each type of material.
Light curable adhesives are typically cured using electromagnetic energy in the UV and
visible ranges of 250 to 450 nanometers (nm). It should be noted that ultraviolet light is easily
attenuated when attempting its transmission through any materials that are not extremely
transparent or optically pure. Even window glass will have reduced transmission or block
most UV wavelengths, and this attenuation is greater as wavelengths become shorter. For
this reason, applications that call for deep curing through thick adhesives layers require the

Uvitron International PORTA-RAY 400/600W Instruction Manual, Rev. E
Page 10 of 22
THEORY OF OPERATION (CONTINUED)
4
longer light wavelengths in the UV-A and visible ranges for maximum penetration. These
longer wavelengths are also required for curing through more opaque or colored adhesives
and substrate materials to reduce the affect of attenuation. Shorter wavelengths in the UV-B
and UV-C regions have more energy and are effective for curing and removal of surface tack
for thin layers of coatings, inks and paints.
To allow the PortaRay curing system to adapt to these different types of curing applications,
multiple replacement lamp types are available which are optimized for each of the visible,
UVA and UVB wavelength ranges. See the Accessories list in section 9.2 for ordering part
numbers of the optional lamp types.

4.2 System Information
The PortaRay has a very high power density light output, which will result in rapid, high bond
strength cures. The unit utilizes a metal halide type arc lamp, which is powered by a tightly
regulated switch-mode power supply. This combination provides very consistent light output,
which results in very repeatable cure times.
The system is available in 400 or 600 Watt lamp power, allowing for the matching of output
power and heat levels to an application’s curing requirements. Lamp reflectors are available
in either parabolic type for uniform flooding of large areas, or in a focused reflector type for
concentrating maximum intensity onto smaller spots. The light intensity can be controlled with
the top panel power level select switch, or by adjusting the distance of the lamp head to the
substrate being cured (larger distance results in lower light density and intensity).
Because the PortaRay is designed to be portable and extremely easy to transport and carry
between departments or to distant locations, the system is also available with an optional
accessories storage compartment that can be latched to the bottom of the lamp housing. This
storage box can be used to house curing system accessories such as the power cord,
headrest, UV safety glasses, gloves, adhesive syringes, etc., allowing for easier storing and
carrying of all system components in one small briefcase-like carrying unit.

Description
1. Handle
The PortaRay handle can be used to carry the curing system
when the lamp head is latched to bottom accessory
compartment, or to hold the lamp head during manual curing
operations.
2. Mounting Holes
These threaded holes can be used for fastening the lamp head
to a stand, fixture, machine or conveyor (refer to section 2.2).
3. Lamp Power Select Switch
The Lamp Power rocker switch selects either the “full” or
“standby” lamp power setting. When curing or warming-up the
lamp, the switch should be set to full power. Between curing
operations, the switch can be set to the low power standby
setting which reduces the amount of heat and stray UV light
radiated by the unit. The switch should always be set to
“standby” when the lamp is idling on the headrest. When
switching back to full power, the lamp will be ready for curing
again after a brief 5 to 10 second re-warming period.
4. Input Power Switch &
Receptacle
The Input Power switch is used to apply or remove main power
to the PortaRay system. Co-located with the switch is the IEC
type power cord socket where the input line cord is inserted.
5. Lamp head latches
These latches are used to secure the lamp head to the optional
bottom accessories compartment during transport & storage.
6. Input/output Cooling Air
Louvers
The input & output air louvers channel fan cooling air in and out
of the lamp head. These must remain unobstructed. Air enters
from the sides and exhausts from the bottom of the housing.
7. Cooling Fan
The lamp head fan cools the lamp, reflector and internal power
supply circuit board assembly.
8. Accessories Storage
Compartment (optional)
This bottom box can be used to store and transport curing
accessories (e.g. headrest, glasses, power cord & adhesive).
9. Arc Lamp
Medium pressure arc lamp which produces UV & visible light.
10. Reflector
Lamp reflector which collects and concentrates light from all
sides of the arc lamp. This surface should be kept clean to
insure maximum light output (refer to section 7.2).

SYSTEM OPERATION
6
The PortaRay is designed to be an extremely user-friendly system, which has a minimum of
controls, and is easy to operate. Therefore, the following operating instructions are brief.
6.1 Setup and Operation
A. If using the optional bottom accessories
compartment, open the latches on the side of the
unit, and remove the lamp from the bottom
compartment by lifting it by the handle (see fig. 6).
B. Place the lamp head on the headrest (with the
drawer closed for drawer type rest, see fig. 7).
C. Plug the IEC type connector of the AC Power
Cord, into the power input receptacle in the side
of the lamp head. Plug in the opposite end of the
line cord into a nearby single phase power outlet.
D. To start the system, turn on the Input Power Switch at the side
of the unit. The lamp should turn on.
E. During the warm-up period, the switch on the top of the lamp
should be set to full power mode. A one to two minute warm-up
time is required for the lamp to reach full intensity.
WARNING: Bluish light is projected from the unit
becoming brighter as the unit warms up. This ultra-violet
light can be harmful to the eyes and skin. UV protective
glasses and clothing are required to prevent burns of eyes
and skin. Care should also be taken to protect other
personnel in the area from unintentional exposure to the
UV light (Refer to section 3.1 for additional UV safety
information).
F. To change to the reduced power mode, switch the lamp power rocker switch to the
standby power position (rocker paddle pressed toward the closest handle stem). The lamp
intensity will visibly dim when the unit is in this low power mode.
NOTE: The PortaRay system is designed for continuous operation. It is suggested that
the lamp remain on during work breaks. Frequent stopping and starting of the lamp will
reduce lamp life. In general, leave the unit in standby power mode for periods of non-
use of less than thirty minutes. The unit will require only a brief 5 to10 second re-
warming period before the lamp returns to full intensity. Once the input power is

Page 14 of 22
SYSTEM OPERATION (CONTINUED)
6
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.

MAINTENANCE
7
7.1 Maintenance Considerations
During the production process, various deposits of foreign matter may accumulate on the
lamp and reflector surfaces. Product vapors can also condense on these surfaces over time,
causing poor transmittance/reflectance of UV light, and reduced curing efficiency. To insure
maximum light output of the curing system, these surfaces should be inspected and cleaned
at regular intervals as required.
The lamp will also need to be replaced periodically as its UV output drops sufficiently enough
to prevent complete product curing. A radiometer should be used to monitor system UV light
output over time. If a radiometer is not available, the quality of the product’s curing should be
checked regularly as a less direct indicator of lamp performance. If a radiometer is not used
to track lamp performance, then the lamp should be replaced after approximately every 2000
hours of operation.
7.2 Cleaning of Optics and Lamp Replacement
The following procedure should be followed carefully for optics cleaning & lamp replacement:
WARNING: To avoid coming in contact with dangerous high voltages or high
temperatures, the following power down & cooling procedure must be completed
before attempting any maintenance operations on the PortaRay UV Lamp: Turn off the
input power switch at the side of the lamp head, and unplug the power cord from the
input power receptacle. Wait 15 minutes or until the lamp and other hot components
cool back to room temperature before proceeding with any maintenance operations.
1. Remove the lamp head from its headrest or fixture, and place it upside-down on a soft
clean surface.
CAUTION: It is extremely important to avoid touching (with your hand) the aluminum
reflector, and the glass portion of the lamp. Contaminants from your skin will cause
oxidation of the reflector, and unwanted refraction of light through the contaminated
portion of the filter glass and lamp. These contaminants may also cause localized hot
spots on the quartz envelope of the lamp, which could result in premature lamp failure.
Clean cotton gloves or a clean soft cloth should be used when handling or cleaning the
lamp and reflector.
2. Using cotton gloves or a clean soft cloth, remove the lamp by holding it near one end, and
pushing into the adjacent spring loaded socket. Once the other end of the lamp has
cleared the walls of its socket, tilt the cleared end of the lamp up slightly, and remove the
lamp from the other socket that is still engaged.

MAINTENANCE (CONTINUED)
7
3. Using a clean soft cloth dampened with isopropyl alcohol, clean the surfaces of the
aluminum reflector.
CAUTION: Do not use abrasive cleaning compounds or steel wool for cleaning the
reflector. These harsh products will remove the finish and reduce the reflector efficiency.
4. Wipe the lamp lightly with a clean isopropyl dampened cloth. If the lamp shows signs of
bulging or shape distortion, then replace it. Otherwise, dry and polish the lamp with a
clean dry cloth.
5. Re-insert the cleaned or new lamp between the lamp sockets, with the filler nipple facing
the reflector. Be sure to center each lamp electrode in its socket to insure proper electrical
connection and to avoid arcing (which could damage the lamp or socket). The lamp is
non-polarized so it does not matter which electrode is placed in which socket.
6. Mount the lamp head back on its headrest or fixture, and
reconnect the input power cord.
7. Re-test the unit to insure satisfactory light intensity and
cure time is achieved.
7.3 Accessories Storage, Packaging and Carrying
Once the lamp has cooled sufficiently, the system can be re-
packaged and transported. The optional bottom
compartment of the PortaRay can be used for storing related
curing accessories (such as the headrest, power cord, UV
glasses and adhesive –see fig. 10). After accessories have been inserted, the lamp head
can be latched onto the bottom enclosure for system storage or transportation to another
location (see fig. 11).
