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
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-

After 4 to 6 seconds, the Autotune feature is disabled and the welder enters manual
tuning mode (for further information, refer to Section
