Glossary of Terms

The following terminology may be encountered when using or operating a 2000-series
ultrasonic welding system. Some of these terms may not be available in all configurations:
AB Amplitude: The amplitude at the horn face during the afterburst step.
AB Delay: Time delay between the end of the hold and the start of afterburst.
AB Time: The time duration of the afterburst.
Absolute Distance: The distance the horn has travelled from home.
Absolute Mode: A mode of operation in which the weld is terminated when a user-
specified distance from the home position has been reached.
Absolute Position: The position of the Actuator from the home position.
Accept-as-is: A disposition permitted for a nonconforming item when it can be
established that the item is satisfactory for its intended use without violating safety or
functional requirements.
Actual: A reported value that occurred during the weld cycle. The converse is the set
parameter that was requested during the setup.
Actuator: The section of the Integrated Welder that houses the converter, booster, and
horn assembly in a rigid mounting allowing it to move up and down either mechanically or
pneumatically to apply a predetermined pressure on the workpiece.
Afterburst: Ultrasonic energy applied after the hold step. Used to break away sticking
parts from the tooling.
Alarm Beeper: An audible signal that sounds when a general alarm has occurred.
Amplitude: The peak-to-peak movement at the horn face. Always expressed as a
percentage of the maximum.
Amp Control: The ability to set amplitude digitally or by an external control.
Automatic: A pretrigger condition indicating that pretrigger engages when the actuator
leaves the upper limit switch.
Beep: An audible signal produced by the Branson control board. Used to alert the
operator to an unexpected condition or that trigger has been reached.
Booster: A one-half wavelength long resonant metal section mounted between the
converter and horn, usually having a change in cross-sectional area between the input
and output surfaces. Mechanically alters the amplitude of vibration at the driving surface
of the converter.
Clamping Force: The pressure exerted by the horn on the workpiece.
Cold Start: A user operation to establish a setup to a new, initial minimum set of weld
parameters. Refer to
carefully.
Collapse Distance: The vertical distance your part will be collapsed before termination of
ultrasonics.
Collapse Mode: A mode of operation in which the weld is terminated when the part has
been collapsed by a user-specified distance.
Custom Logic: Allows the operator to choose either High (24V) or Low (0V) logic for
switches to be used in interfacing the welder to an automated system.
Cycle Aborts: There are no cycle aborts except Ground Detect, which is available in IW
only.
