2.3 Features of the System
Listed below are many features of the Branson 2000X-series ultrasonic welding system
included in a 2000X aed Actuator and 2000X distance Power Supply.
• Autotuning: Branson Power Supply tuning ensures that the system is running at peak efficiency
• Amplitude Stepping: A patented Branson process, controlled by the Power Supply. At a
specified time, energy, peak power, distance, or by external signal you can change the amplitude
during the weld to control the flow of plastic. This feature helps ensure part consistency, higher
strength parts and control of flash
• Digital Horn Test Diagnostics: In Test mode of the Power Supply, you can view the Horn Test
results in digital form, using digital readouts and bar graphs on the Power Supply to give you the
best picture of the stack’s operation
• Pretrigger: This feature allows you to set the system weld controls to turn the ultrasonics on
before contact with the part
• Afterburst: This feature allows you to set the system weld controls to turn the ultrasonics on
after the weld and hold steps to release parts from the horn
• Control Limits: With some power supply models, these secondary controls are used in
conjunction with the main parameters of the weld parameters. These user-programmed limits
provide for adaptive control of the weld process
• Process Alarm Display Showing Actual and Set Values: When an alarm condition has
occurred, you can view the value for the last weld and the suspect and reject settings you
programmed into the controls
• Post Weld Seek: This system feature provides a short burst of energy at the end of the weld
Hold and Afterburst steps to automatically retune the power supply, if required
• Frequency Offset: This process feature allows a user to set a frequency value, for certain
specific applications, where the force imparted on the fixture or anvil causes a frequency shift in
the Stack’s operation. You should only use this feature when advised to do so by Branson
• English (USCS)/Metric Units: This feature allows the welder to be set up in the local units in
use
• Startup Diagnostics: At power supply startup, the controls test the major system components,
including the Actuator and its controls
• Weld Parameter Entry through Digital Keypad: User Setup is direct and easy, by selecting
the menu parameter by name and using the keypad to enter the precise value. The controls also
support entry by incrementing existing values
• System Information Screen: This is a screen that will give you information about your welding
system (e.g., cylinder size, stroke length, number of cycles). Refer to this screen when
contacting Branson for service and support
• Ramp Starting: The starting of the 2000X-series power supply and horn is done at the optimum
rate to reduce electrical and mechanical stress on the system. This also helps make some tough-
to-start applications possible
• True Wattmeter: The controls on the power supply include a true wattmeter for accurate
measurement of power and energy
• S-Beam Load Cell/Dynamic Follow Through: The load cell allows the ultrasonics to be
triggered at a designated force input into the power supply
• Encoder: Allows the power supply to monitor the distance the horn has travelled, enabling the
use of distance functions
• Downspeed: Controls the rate of descent and force build-up on the part
• Pressure Sensor: Allows the power supply to read the system pressure
