NPACKING AND INSPECTION
Before unpacking the equipment check the shipping carton for any visible
damage. If you see any be sure to follow the procedures described below
under “Visible Loss or Damage.” Otherwise proceed to remove the
equipment from the carton. Before storing any packing material check it
carefully for small parts. Then perform a visual inspection of the equipment
to detect any evidence of damage which might have occurred during
shipment. Check the following:
1. all components against the enclosed packing list
2. all module plug-in units
3. all wire plug-in connections.
The equipment was carefully packed and thoroughly inspected before
leaving our factory. All units are tested and checked for problems prior to
shipping. It is asked that when a problem does occur that all parts and
components be inspected for damage (especially when the unit is not in
working order when received). Responsibility for safe delivery was assumed
by the carrier upon acceptance of the shipment. Claims for loss of damage
sustained in transit must therefore be made upon the carrier as follows:
VISIBLE LOSS OR DAMAGE
Any external evidence of loss or damage must be noted on the freight bill or
express receipt and signed by the carrier’s agent. Failure to adequately
describe such external evidence of loss or damage may result in the carrier’s
refusal to honor a damage claim. The form required to file such a claim will
be supplied by the carrier.
CONCEALED LOSS OR DAMAGE
Concealed loss or damage means loss or damage which does not become
apparent until the merchandise has been unpacked. The contents might
have been damaged in transit due to rough handling even though the
container may not show external damage. When the damage is discovered
upon unpacking make a written request for inspection by the carrier’s agent
within 48 hours of the delivery date. Then file a claim with the carrier since
such damage is the carrier’s responsibility. The form required to file such a
claim will be supplied by the carrier. Do not destroy packing materials or
move material from one location to another before the carrier makes their
inspection.
If the system or any unit is damaged notify Sonics. Sonics will arrange for
repair or replacement of damaged equipment without waiting for the claim
against the carrier to be settled provided a new purchase order is issued to
cover the repair or replacement costs. Should any damage shortage or
discrepancy exist please notify us immediately.
NOTE: We
recommend keeping
all carton(s) and
packing material in
case it mig t be
necessary to move
t e equipment, or to
s ip it for repair.

INTROD CTION
The GXL power supply is an ultrasonic generator with automatic frequency
tuning and a built-in Microprocessor that features time energy and distance
controls. The Microprocessor is programmed with a multi-function keypad
and information is displayed on the back-lit liquid crystal display (LCD). This
power supply can be used with a pneumatic press or actuator or with a
stand-alone converter. (Note: Distance controls are not available with a
stand-alone converter.)
OVERVIEW OF LTRASONIC PLASTICS
ASSEMBLY
WHAT IS ULTRASONICS?
Ultrasonics refers to vibrational waves with a frequency above the human
audible range which is usually above 18 000 cycles per second (Hz).
PRINCIPLE OF ULTRASONIC ASSEMBLY
The basic principle of ultrasonic assembly involves conversion of high
frequency electrical energy to high frequency mechanical energy in the form
of reciprocating vertical motion which when applied to a thermoplastic
generates frictional heat at the plastic/plastic or plastic/metal interface. In
ultrasonic welding this frictional heat melts the plastic allowing the two
surfaces to fuse together; in ultrasonic staking or insertion the controlled
flow of molten plastic is used to capture or lock another material in place
(staking) or encapsulate a metal insert (insertion).
ULTRASONIC ASSEMBLY SYSTEMS
Sonics ultrasonic assembly systems are generally composed of the following
major elements: a power supply converter booster horn pneumatic press
and holding fixture as detailed in the diagram on the next page. A review of
this diagram will help you understand the basic elements involved in the
assembly process and their relation to each other.

GLOSSARY OF LTRASONIC TERMS
POWER SUPPLY/GENERATOR – The solid state power supply converts
standard 50/60 Hz electrical energy to 15 000 Hz 20 000 Hz or 40 000 Hz
(15/20/40 kHz) electrical energy.
ACTUATOR/WELDING PRESS – The pneumatic actuator provides com-
pressive force and mounting for the converter booster and horn assembly.
The tabletop press consists of a base assembly column and actuator (head).
CONVERTER – The converter changes the high frequency electrical energy
supplied by the power supply to high frequency mechanical vibrations.
BOOSTER – Successful ultrasonic welding often depends on having the
right amplitude at the horn face. Often it is not possible to design a horn
which has both the necessary shape and required gain (ratios of input
amplitude to output amplitude). In such cases a booster is placed between
the converter and the horn to either increase or decrease the amplitude of
the horn. In addition to changing/maintaining the amplitude the booster
provides support and alignment in the welding system.
HORN – The horn is a tuned component of the system which comes in
contact with the parts to be assembled. The horn 1) transfers the ultrasonic
vibrations produced from the converter to the parts being welded and 2)
applies necessary force to the assembly while the material resolidifies.
HOLDING FIXTURE – The holding fixture or nest assures proper alignment
and support of the parts being assembled.

INSTALLATION
ELECTRICAL POWER REQUIREMENTS
The power supply requires a fused single-phase standard 3-terminal
grounding type receptacle capable of supplying the requisite voltage and
current. Refer to the table below for power specification.
SETTING UP
The power supply is a free-standing assembly. It should be installed in a
clear uncluttered location that is free from excessive dirt dust corrosive
fumes and temperature and humidity extremes. The selected installation site
should be near the electrical power source and away from equipment that
generates abnormally high electrical transients. Observe the following
additional instructions when installing the equipment:
a. Allow at least 6 inches (152.4mm) at the rear of the power supply for cable
connections.
b. Position the power supply so that the front panel controls are visible and
readily accessible.
c. The power supply is air cooled; allow sufficient space around the
assembly to ensure adequate ventilation. If the power supply must be
housed in a confined space forced air cooling may be necessary to keep
surrounding air within acceptable ambient temperature limits. Periodically
check the ventilation grille and clean as necessary.

INITIAL OPERATION
After the power supply is turned on (as described on previous page) follow
these steps:
1. Make sure that all necessary preparations have been made with regard to
the ultrasonic system and tooling and that the items to be welded are in
position.
2. Press and hold the TEST button. While depressing the TEST button
check the LCD display. Make sure the bar graph indicator on the LCD
display (a series of vertical lines that register to the 0 to 100% load meter
scale – see example below) does not exceed 20%.
During the testing process keep in mind that the ultrasonics are only
activated as long as the TEST button is depressed – once you release the
TEST button ultrasonics is terminated.
A bar graph indicator reading of above 20% signals that there may be a
problem with the stack. Check your assembly and re-test.

INSTRUCTION MANUAL • MODEL GXL POWER SUPPLY 19
The Alarm screen displays information about the alarm(s) that have been
triggered by the system encountering parameters outside of the specified
tolerance limits. The screen will indicate whether alarms occurred in Time
Distance or Energy. If there are no alarms dashes will display. If there are
alarms an L (for Low limit indicating that the low limit was violated) and/or
an H (for High limit indicating that the high limit was violated) will display by
the applicable mode (time distance or energy). When a new cycle begins
the system will automatically clear the current alarm.
Counter Screen
The Counter screen displays information about the job number the number
of cycles run to date the customer resettable counter (CRC) and the
resettable alarm counter (RAC). The 2 resettable counters can be reset
whenever desired by pressing the Clear key when the counter screen is
displayed. (The keypad must be unlocked.)
RELATIONSHIP OF TIME, DISTANCE AND ENERGY
SETTINGS
Parameters can be set in the time distance and/or energy menus. The
settings in all of these menus should be taken into account when you are
setting up a job since they do not function independently of each other and
a parameter in one menu can impact the effect of a parameter in another
menu.
For example if you specify a weld time of 2 seconds an energy setting of
2 000 joules and clear any previous distance settings (so that only dashes
appear in the distance menu settings) the weld cycle will be terminated by
whichever of the 2 settings (Weld Time or Energy Setting) is reached first –
that is either when ultrasonics have been applied for 2 seconds or when
energy equivalent to 2 000 joules has been delivered to the parts being
assembled. If 2 seconds is reached before 2 000 joules have been delivered
the weld cycle will terminate regardless of the amount of energy delivered
and vice versa.
The start-up ready screen which shows the last weld information will show a
flashing “sec” or “J” to indicate which setting was achieved first and thereby
terminated the weld cycle. In the example above if the weld time of 2
seconds is reached before 2000 joules have been delivered the ready screen
