Pre-Trigger Control (Optional)
The pre-trigger control turns the ultrasound on at a preset
point in the thruster downstroke. This control is normally
used in staking and inserting applications. This control
should be set for a distance of approximately 6.25 mm
(.25 inch) above the part.
Trigger Control
Setting the trigger control determines the amount of pre-
load on the part before turning on the ultrasonics.

The actual amount of force applied
to the part depends on the following
four factors:
• The setting of the regulator(s)
• The area of the air cylinder
• The mass of the horn used
• The surface area of the horn
The pre-trigger switch option starts
the horn vibrating before contacting
the part to be welded. To ensure
safe operation, adjust the pre-trig-
ger so the ultrasound signal will not
activate if the horn is more than ¼ in
(7 mm) from the part to be welded.
