Features of the System
Dynamic Triggering and Follow-Through
Many welding applications require force to be built up on the part before ultrasonic energy is
activated. To achieve this, the Actuator contains a dynamic triggering mechanism located
between the air cylinder and the converter, which initiates (triggers) ultrasonics after a preset
force is applied to the part. Dynamic follow-through maintains a consistent force on the part
during the weld collapse. This system helps provide uniform weld quality.
The dynamic triggering and follow-through process operates as follows: upon activation of the
operating cycle, the solenoid valve delivers system air to the upper portion of the cylinder, and
proportional air to lower portion of the cylinder, causing the horn to advance and contact the
workpiece. As the pressure increases, the cylinder compresses springs, forcing a cam to break
the optical beam of the trigger switch. When the trigger switch closes, a signal is sent to the
Power Supply, which then starts the weld cycle. At this time, the actuator locks into a cycle, tim-
ing begins, and the palm buttons can be released. As melting of the plastic occurs, spring reac-
tion the follow through maintains consistent force on the part, ensuring smooth, efficient
transmission of ultrasonic energy into the part.
2.3 Features of the System
Listed below are many features of the Branson 2000X-series ultrasonic welding system included
in a ao2000X ao Actuator and 2000X Series Power Supply.
• 19” Rack Mount Enclosure: Compatible with industry standard 19” rack enclosure
systems.
• Vacuum Fluorescent Display: For good visibility in any factory lighting situation.
• Membrane Keyboard: For high reliability and immunity from factory dust
and oils.
• Digital Tuning: An advanced means to tune the Power Supply for applications and
horns at the extremes of the Power Supply capture range.
• Autotuning: Branson Power Supply tuning ensures that the system is running at
peak efficiency.
• Weld Modes: This welder offers multiple weld modes so that you can choose the
best mode of control that meets your specific application need: Time, Energy, Peak
Power, and Ground Detect.
• Print on Alarm: You can request any printable items whenever an alarm occurs.
This will give you the information you need to determine how your setup or limits can
be changed.
• Print on Sample: You can request any printable items based on a sampling rate.
This facilitates auditing your process and lot control.
