5. Press the TEST key. The ultrasonics will be activated and the red LED will
light up during the weld cycle. The actual wattage will be digitally displayed
on the LCD screen and the bar graph line will indicate the corresponding
power output percentage.
6. Press the ENTER/REVIEW key after the TEST cycle is completed and
the LCD screen will display the peak wattage consumed and the weld time,
like the example below.
Use the amplitude control dial to adjust the output as necessary. When the
switch on the hand gun is depressed, the LCD screen will display the
amplitude percentage like the example below:
7. If test readings do not exceed the maximum allowable values, proceed to
actual weld operation as follows:
a. Bring the hand gun in contact with the surface of the item(s) to be
assembled and apply light guiding pressure.
b. Depress the trigger switch on the hand gun to activate the ultrasonics.
8. Examine results, and if necessary, adjust time and amplitude settings,
and/or force where applicable.
