4.4.2 Connecting Tips, Horns, and Converters
Connecting the Horn to the Converter
To connect the horn to the converter, take the following steps:
A standard flat tip, recommended for processing liquids, is supplied with tapped horns. Other
tip configurations are available for experimental work on applications where the ultrasonic
vibrations are transmitted directly into the solution. The shape of the horn influences the direc-
tion in which the ultrasonic vibrations are delivered from the horn.
Connecting the Tip to the Horn
To attach the tip to the horn, take the following steps:
Step Action
1
Clean the contacting surfaces of the converter and horn, and remove any
foreign matter from the threaded stud and threaded hole.
2
Coat one of the mating surfaces completely with a very thin film of silicone
grease (without additives), using an amount about the size of a paper
match head. Excessive silicone grease can diminish performance.
3
Thread the horn stud into the converter and tighten, using spanner
wrenches. The recommended torque is 220 inch-pounds (24.85 Nm).
Step Action
1
Clean contacting surfaces of the horn and tip, and remove any foreign
matter from the threaded stud and threaded hole.
CAUTION
j
The tip must be installed clean and dry, or the power supply
may not tune and operate correctly.
2
Hand-assemble the tip to the horn.
3
Using a spanner wrench on the horn and an open-end wrench on the tip,
tighten the tip. See Figure 4.3. Torque specifications for the various
threaded tips follow:
1/4-20 — tighten at 90 inch-lbs./10.16 Newton-meters
3/8-24 — tighten at 180 inch-lbs./20.33 Newton-meters
