Hydraulic Slow Speed Adjustment
The hydraulic slow speed adjustment is an integral part
of the optional hydraulic slow speed control. It sets the
amount of velocity damping of the hydraulic unit. (See
Figure 4-11.) For detailed information on this adjustment,
refer to Section 6: Options.
Mechanical Stop Adjustment
The function of the mechanical stop is to halt the down-
stroke at a predetermined point. It is used in two ways:
• To stop the downstroke at a particular depth of travel
relative to the fixture/anvil.
• To prevent the horn from contacting the fixture when
there is no part present. This prevents possible dam-
age to the horn and/or fixture. Never allow the horn to
contact the fixture while ultrasonic power is applied
to the horn. Metal–to–metal contact can void the horn
and/or tooling warranty.
Pressure 1 Regulator
Pressure 1 regulator is used to set the amount of air pres-
sure applied to the air cylinder during the press downstroke
and weld cycle.
Pressure 2 Regulator
In some applications the Pressure 2 regulator is set to be
maintained during the hold portion of the weld cycle.
Regulator Select Switch
The Regulator Select switch is used to select Pressure 1
regulator (Weld Pressure) or Pressure 2 regulator (Hold
Pressure) to set the required pressure on each regulator
and for monitoring the pressure gauge.

CAUTION
Do not allow the horn to con-
tact the fixture while ultrasonic
power is applied to the horn.
