Press the Energy key again (and successively after each menu display) to
advance to these next screen displays.
Energy Limit Low – sets the low energy alarm examination point (as a
process control tolerance limit). An energy alarm will be triggered if the actual
weld energy is less than this value. By specifying values for this limit and the
Energy Limit High, a weld energy “window” can be created in which a ”good
weld” can occur. (If no alarms are triggered – the weld cycle occurred within
the designated energy limits.)
Energy Limit High – sets the high energy alarm examination point (see Limit
Low above). An energy alarm will be triggered if the actual weld energy is
greater than this value.
Energy Cal(ibration) Pulse – The system calibrates itself prior to each weld
cycle. The use of the calibration (cal) pulse enables the machine to
automatically monitor the idle losses in the converter/booster/horn assembly
just as the horn begins its descent to the part. The system subtracts the
energy necessary to vibrate the horn in air from the total energy programmed
to weld a part. The cal pulse may be activated during all modes of operation.
Occasionally, it may be necessary to turn the cal pulse off. For example, in
order to place a part into the horn prior to welding (i.e., vacuum horns), the
cal pulse can be turned off as described below.
The display will read either “ENERGY CAL PULSE ON” or “ENERGY CAL
PULSE OFF.” Press either the Up or Down arrow key (which will act as a
toggle) and the cal pulse display will show either “on” or “off.” When the
desired setting is shown, press the Enter key to enter your selection.
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.
NOTE: Major
adjustments of
amplitude and
pressure are made on
the press through the
use of boosters and
pressure controls.
