902J Branson Type Converter 20khz Replacement 1000w Ultrasonic Welding Unit
Description:
Replacement Branson 902J Converter .
Replacement converter for Branson model 902J (101-135-047), for use with 910IW or IW+ intergrated benchtop welders or 905 or 910 D/M (500 and 1000 watt) power supplies using actuator or assembly stand units.
All of the components used in construction of these Branson 902J replacement converters are all new, not recovered from scrapped units.
Ultrasonic Converters and Ultrasonic Transducers are one in the same. Converters or Transducers all do the same thing convert electrical energy to mechanical movement. so we have our electrical charge being introduced across the surface of the ceramics at the desired frequency which in turn gives us a movement or vibration at the working end on the converter.

Assembly precautions for Ultrasonic transducer parts:
The main parts of the ultrasonic vibration system, such as transducers, horns, tool heads, etc., are connected by a central bolt.
1. Check that the contact surface should be smooth and free of scratches. If there are any scratches, use a metallographic paper with a number of zero or more to lightly polish. It is required to smooth the defect without damaging the flatness of the contact surface.
2. Clean the screws, screw holes and contact surfaces with a volatile, non-corrosive detergent.
3. Thoroughly clean the screws, screw holes and contact surfaces.
4. All connecting screw holes should be perpendicular to the contact surface.
5. Apply a thin layer of butter or Vaseline to the contact surface before tightening. Do not apply to the connecting screws and screw holes.
6. Carefully tighten the two parts. Adjust the appropriate tightening torque according to the specifications of the connecting screws. When possible, tighten it properly.
7. If you loosen the joint surface again, you should not see any scars.
8. The amplitude of the vibration system is evenly distributed by hand, no strange sound, no local severe fever.
9. After re-opening the joint surface after working for a period of time, there should be no signs of oxidation or ablation. Otherwise, the contact here is not good, and the ultrasonic energy is seriously lost here.
