to begin at one level and finish at another, you can “fine tune” your overall welding
procedure without making changes to your tooling (converter, booster, horn, or fixture).
6.9.15 Step Pressure
You can select whether you want to apply a fixed or stepped pressure to the part during
welding. If Step was selected ON from the Weld Setup page the following screens will be
shown. Pressing Pressure displays a screen with two choices, STEP or FIXED. If FIXED was
selected ON from Weld Setup, the screen with 2 choices, STEP or FIXED is displayed. If
you choose to use a stepped pressure, you must also choose the first and second
amplitudes (each as PSI) to use before and after the step point, as well as the criteria to
use the step.
Figure 6.7 Pressure Step
NOTICE
You can select the amplitude to use only when Amplitude is set to
Fixed. If amplitude is Stepped, this parameter is inactive and the
display shows *** for Amplitude.
NOTICE
If you set Amplitude Control to External in System Configuration, this
parameter is inactive and the display shows Ext for Amplitude (%).
