8.0 Overview of the Stepper Controls TOC – The stepper front panel is shown below. It contains
several switches and an LCD display necessary to initiate setup functions that are used to align the parts and
fixture and to teach the system where the parts are located (the distance to the unwelded parts).
The “Align” button is used first to extend the ultrasonic horn by the programmed travel distance toward the
parts. Adjust the ultrasonic horn for proper fit against the unwelded parts and lock the head assembly into
position using the column lock handle. Apply enough pressure to the lock handle so the head will not be able
to move under normal welding pressures. Then use the “Home” button to return the head to the home or full
up position.
The operator must then use the “Teach” button to execute the Teach Function. This function must be used
one time after initial alignment or whenever the column, fixture or parts are changed or adjusted. The system
will learn where to find the parts by extending the head assembly until force is detected on the parts. This
position will be remembered for subsequent weld cycles or until the teach function is repeated at a later time.
The settings are preserved in permanent memory and will be saved during any non powered interval.
Once the system knows where the parts are located and the expected variation in their vertical dimension
(upper and lower tolerance settings) the production welding process will be accurately repeated for every weld
cycle.

8.1 On/Off Button
– The On/Off button turns the unit on and off.
8.2 LCD Display
– The LCD display will show the weld distance report after every cycle. In addition, the
display shows instructions and feedback in accordance with the operations in progress. It is also used to
examine the presently programmed weld parameters so that a computer is not required once a system has
been setup for production operations.
8.3 Align Button
- The Align button is used to initiate the Align function (when used in coordination with
the palm buttons) or to examine weld setting parameters.
View settings -
To view settings, as instructed on the display, press and hold the Align button for 2
seconds, then release. The LCD screen will then display a weld parameter, such as Force Trigger.
Then press the Align button to scroll through the present settings. Press the Home button to leave
