AMPLITUDE/PRESSURE
Fine adjustments of the following amplitude and pressure settings can be
made by using the Amplitude/Pressure key. All settings range from 20%
(minimum) to 100% (maximum).
Amplitude Ramp – (only on systems configured for more than 2200 watts)
Used primarily for 15 kHz systems to ensure a slow start-up when welding
with big horns.
Trigger Force (Press) – this setting can be used to specify the pressure that
needs to be reached to trigger the ultrasonics when “Force/Pressure” has
been selected as the Trigger mode.
Amplitude Setting – this setting is used to specify the vibrational amplitude.
TRIGGER
Selection of the trigger mode is achieved by pressing the Trigger Key and
then using the Up/Down arrow keys as a toggle to select one of the following
modes to act as the trigger to start ultrasonics.
Delay Timer – selecting this mode means that the ultrasonics will be
triggered when the Delay Time specified in the Time menu is reached.
Force/Pressure – selecting this mode means that the ultrasonics will be
triggered when the Trigger Force (Pressure) specified in the Amplitude/
Pressure menu is achieved.
Pretrigger - Top – selecting this mode means that the ultrasonics will be
triggered as soon as the head assembly leaves its home (head up) position
and starts descent. This means that ultrasonics will be on before contact is
made with the parts to be welded.
NOTE: Major
adjustments of
amplitude and pressure
are made on the press
through the use of
boosters and pressure
controls.
