tracking, real-time energy monitoring, power digital display, and
touch screen interface control. Make the operator be familiar
with the generator soon.
In order to operate and maintain this product correctly, and
ensure your safety, please read this manual carefully before
using it. Pay special attention to the description of this graphic
symbol in the text, and please save it properly and check it
later. This will help to provide you with a comprehensive

Any operate not been trained by our company can’t debug and
maintain this generator. Any improper operation will cause the
machine to operate abnormally, malfunction or damage, or
even cause an accident!
This manual including the description and operation of the
HZ-2000 digital ultrasonic generator. If you can’t solve the
problem during operating , please contact our company for
solution. Our email: [e-mail]. We will reply

you in 24 hours.
Attentions
1. Before making any electrical connection, please make sure
that the power supply is off. Use a grounded power socket
to prevent electric shock.
2. The ultrasonic generator will generate high voltage,
non-professionals do not open the casing!
3. Do not switch on the machine when the horn is loose, to
avoid abnormality when opening it. When the machine
under abnormal conditions, do not turn it on again before
the problem solved!
4. Do not put your hand under the welding horn, the
downward pressure and the high frequency vibration may
cause a safety accident!
5. Do not make ultrasonic test when the external cable ( the
high frequency line) is not connected!
6. Do not place your hands between the welding horn and the
mold during working or testing. This machine must be
operated by one person during the horn adjustment,
debugging, or production, prohibit multiple people
operating and debugging at the same time!

Working principle
The ultrasonic generator generates the signal frequency
required by the ultrasonic transducer, and then uses the
thermoplasticity of the plastic to generate heat at a very high
speed between the molecules by using high-frequency friction
between the working surfaces. When the heat is sufficient to
melt, the ultrasonic wave is stopped. Vibration, at this time the
workpiece joint is solidified by melting, complete the
processing procedure! The traditional ultrasonic generator is
manually frequency-modulated, and HZ-2000 digital ultrasonic
generator realizes automatic frequency tracking, real-time
power display, and friendly communication of human-machine
interface!
The frequencies commonly used for plastic processing are 15
kHz and 20 kHz, of which 20 kHz is outside the human hearing
range, so it is called ultrasonic, but 15 kHz is still in the human
hearing range.

B. The following functions can be adjusted
1：Touch（COUNT RESET）Cursor can zero the current processing
quantity
2：Touch（Sonic Test）cursor can read the current frequency. When this
button is pressed, the frequency is searched first and then waved!
Note: You cannot press this button with-loading! In order to avoid
frequency search deviation.
3：Touch（Auto）cursor can be switched to the mode adjustment state.
Under this display, the machine is in the manual state, and the
welding parameters cannot be adjusted! Can be used for horn
adjustment! (Hint: When it is automatic, it can be adjusted when it is
not working)
4：Touch（Reset）Cursor alarming remove. If the alarm can not be
cleared when the overload occurs, or the search frequency cannot be
searched, turn off the power and start it again after 3 minutes.
5：Touch（Set）Cursor, settings interface appear

This page is time model
The following parameters can be adjusted according to the application.
Description: Time model: when welding products, use melting
time to control the welding time of the product
Noted：when the delay time is 0，the delay time will be no
ultrasonic.
This page is energy model
The following parameters can be adjusted according to the application.

Energy model：when welding products, the delay time and the
holding time are also be set. When welding the product, the
welding is balanced by the currently energy. When the welding
energy is reached, the ultrasonic is stopped.

to control the ultrasonic. When the welding energy is reached, the
ultrasonic is stopped.
Continuous mode: When this mode is selected, the machine is
long-vibration ultrasonic with no delay time and hardening time. Tips:
The latter two modes are used in special cases, it is recommended to use
the time mode! )
Secondary delay: secondary delay time setting
Secondary ultrasound: secondary ultrasound time setting
Secondary pressure holding: secondary pressure holding time setting
(Special note: when the secondary delay time is set to 0, there will be no
second welding)

Problem & Solution
First: When the frequency can not be searched, please first remove the h
orn, check whether the frequency of the horn is within the scope of
the machine search.
Second: When the machine alarms, please check whether there are crac
ks,on the horn itself, and whether the power of the generator is exce
eded when welding the adhesive parts of the horn, and replace the l
arger power box.
Third: When the touch screen is poor communication, please check whet
her the communication line is plugged. After plugging in the commun
icate line, turn off the power for three minutes and restart it.
Fourth: When the horn is not available, Press ultrasonic
test, the alarm or in big
power percentage , or the frequency can not be searched, we can jud
ge that there is a problem with the ultrasonic generator, please conta
ct our company!
Fifth: When the ultrasonic effect not
good, please check the following aspects:
1: Plastic material.
2: Whether the design of ultrasonic line is reasonable or not.
3: Accuracy of mode adjustment.
4: Whether the horn design is reasonable or not.
5: The amplitude of the horn.
6: Design of contact surface and interface.

7: Whether the shape and size of rubber parts are deformed or not.
8: Surface cleaning and treatment (as baking paint or electroplating).
9: Energy transferred to the adhesive.
10: Fusion of plastics of different materials.
Please pay attention to safety, prevent hand bruises! If you have any que
stions, contacts us anytime.
