UNPACKING 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 disposing of 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 might be
necessary to move the
equipment, or to ship it
for repair.

INTRODUCTION
The models H520T and H540T are portable 500 watt, hand held ultrasonic
welders used for plastics assembly. Both models consist of an ultrasonic
power supply and a hand gun. These units are designed specifically for
welding, staking, inserting and spot welding applications (refer to the
Applications section of this manual beginning on page 26 for more
information on these operations).
The model H520T is a 20 kHz power supply that comes with the CV55 hand
gun. The CV55 hand gun is supplied with an integral 1/2" (12.7mm) diameter
titanium front driver with a replaceable flat face tip. (Other standard or
custom tips are available.)
The model H540T is a 40 kHz power supply that comes with the CVG54 hand
gun. The CVG54 hand gun is supplied with a removable horn designed
specifically for each customer’s requirements. The higher frequency and
lower amplitude of the 40 kHz system makes it ideal for welding small
assemblies that require gentler action.
The power supplies of both models feature autotune circuitry.
OVERVIE OF ULTRASONIC PLASTICS
ASSEMBLY
WHAT IS LTRASONICS?
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 LTRASONIC 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).
LTRASONIC HAND HELD WELDERS
“Sonics” ultrasonic hand held welders are generally composed of the
following major elements a power supply, hand gun (converter), and horn
(H540T only) 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 ULTRASONIC TERMS
POWER S PPLY/GENERATOR – The solid state power supply converts
standard 50/60 Hz electrical power to 20,000 Hz or 40,000 Hz (20/40 kHz)
electrical energy.
CONVERTER – The converter changes the high frequency electrical energy
supplied by the power supply to high frequency mechanical vibrations.
TIP/HORN – The tip/horn is a tuned component of the system which comes
in contact with the parts to be assembled. The tip/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.
AMPLIT DE – The peak to peak excursion of a horn at its output face.

INSTALLATION AND SET UP
ELECTRICAL POWER REQ IREMENTS
The power supply requires a fused, single-phase, standard 3-terminal
grounding type receptacle capable of supplying the requisite voltage and
current. (Standard 120 volts or optional 220 volts, 50/60 Hz, regulated
between 95-135 volts or 190-265 volts, respectively.)
SETTING P
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.
ELECTRICAL CONNECTIONS
When making the initial electrical connections, make sure the power is
disconnected and follow these precautions.
1. Do not strain or kink the cables. When going around corners, allow as
wide a bend as possible. Do not run the cables parallel to any power line
within a distance of less than 1 foot (305mm).
2. To prevent the possibility of an electrical shock, ensure that the power
supply line cord is properly grounded. Also make sure that the voltage
rating of the electrical power source matches the power supply
requirement.
3. Check with your electrician if you have any wiring questions.
he line cord of the
controller/power supply
is equipped with a
3-prong, grounding
plug. Do not, under any
circumstances, remove
the ground prong. he
plug must be plugged
into a mating 3-prong,
grounding type outlet.
If power supply is to be
run continuously, air
cooling of the converter
and horn is required.
Use clean, dry
compressed air filtered
down to 5 microns.
Do not plug the power
supply into an
electrical outlet until all
other connections have
been made.

OPERATING PROCEDURES
FRONT PANEL CONTROLS AND INDICATORS
Located at the front of the power supply are the following controls
1. ON/OFF switch which turns the power supply on and off. The switch
remains in a “latched state” even if power is interrupted or disconnected.
For example, if the unit is switched on and is then disconnected from the
power source, once it is reconnected to power, the unit will be on.
Likewise, if the unit is off and then disconnected, it will remain off when
reconnected to power until the ON switch is pressed.
2. LCD SCREEN which displays various settings, parameters and prompts
as detailed in the following pages. In addition, during the weld process it
displays a load meter indicator showing the power level of ultrasonics that
is being delivered to the welder (see #3 below).
3. LOAD METER SCALE from 0 to 100% which (in conjunction with
vertical line indicators on LCD display) shows the running power (bar
graph at bottom of display) and peak power (single vertical line at top of
display) during the weld. Peak power is reported as %Pmax after the cycle
(see page 21).
4. TIME key which allows selection and display of time settings and permits
adjustment of time duration in .01 second increments (from 00.00 to 99.99
seconds) for three time parameters as follows
a. Weld time
b. Time Limit Low
c. time Limit High
Do not operate the
power supply unless it
is connected to the
hand gun.
NOTE: he operating
range of amplitude is
20-100%
If ultrasonics are run
continuously (time
setting = 0), be sure to
air cool the converter.
