6.7 Ultrasonic Test
Use the TEST switch on the front panel to measure the ultrasonic energy dissipated by the
stack in air, as long as the welder does not overload. When a welder is operating correctly,
the power dissipated by one specific stack in air should be consistent (±) over a long
period of time. Any change in power indicates that a problem could be developing.
If an overload occurs, and the stack is known to be mechanically sound, the welder may
require manual tuning. (For further information, refer to Section
7.4.1 Manual Tuning.)
To test the welder, make sure that the stack is properly assembled and that all
connections have been made correctly. Then press TEST.
Ultrasonic energy will remain on as long as TEST remains pressed and the welder does not
overload. Pressing TEST causes the POWER BARGRAPH to switch to the DIP Switch-
selected multiplier (for further information, refer to Section 4.11.1 Setting DIP Switches).
After 4 to 6 seconds, the Autotune feature is disabled and the welder enters manual
tuning mode (for further information, refer to Section 7.4.1 Manual Tuning). From this
point on, tuning is controlled by the tuning potentiometer.
CAUTION General Warning
You must have a converter-booster-horn stack installed in you welder
before activating ultrasonic energy.
WARNING General Warning
Ensure that the cover is closed with the door screws secured and that
no one is in contact with the horn when you press TEST. Automated
systems users should turn off indexing equipment for this test.
