Ultrasonic Stack Assembly
Refer to
Figure 4.8 Exploded Ultrasonic Stack Assembly
the ultrasonic stack.
Be sure that the mating surfaces of the horn, booster, and converter are clean and
smooth. Any minor scratches or discolorations can be polished away using Scotch Bright
or 600 grit emery or similar mild abrasive pads. Any gouges, scratches, or chips in any
place on any of the stack components should be analyzed by Branson Metal Welding
personnel.
NOTICE
1. Spread an EXTREMELY thin film of silicone lubricant (Branson P/N 101-053-002) across the
mating surfaces of the horn, booster, and the converter.
2. Hand tighten the converter and horn to the booster. (Make sure that the front and rear
diaphragm springs, the polar mount clamp rings and the nut rings are in place)
3. If the Ultraseal 20 welder is not available to use as a polar mount clamp, then clamp the stack in
a padded vise. (Clamping should be done on the back section of the horn which is approximately
2 inches (50.8mm) in diameter. A moderate clamping force is all that is necessary for this
procedure)
4. Insert the ½" drive torque wrench into the square hole in the spanner wrench, adapter
(Branson P/N 48000-03-011).
5. Set the torque of the wrench to 85 ft-lbs.
6. Place the spanner wrench on the booster and apply torque until the wrench clicks once.
7. The booster is now properly fastened to the horn.
8. Set the torque of the wrench to 55 ft-lbs (75 Newton/Meters).
9. Place the spanner wrench on the converter and apply torque until the wrench clicks once.
10. Attach the clamp rings to the nut rings with the two sets of 12 (M5 X 20mm) socket head bolts.
Torque these bolts to 110 inch pounds (12.4 Newton/Meters).
11. The ultrasonic stack is now assembled.

Never use emery less than 600 grit, sandpaper, harsh abrasives,
grinding equipment, engraving equipment, or debossing equipment
on the stack components. This can cause severe damage to the
machine.
