Ultrasonic Replacement Branson 902J Welding Converter for Plastic Welder
Description:
All of the components used in construction of these Branson 902J replacement converters are all new, not recovered from scrapped units. The parts are made from certified materials in tightly controlled manufacturing processes, assembled and tested in a climate-controlled environment using carefully calibrated equipment, then properly aged and re-tested to ensure performance that duplicates the OEM part. The entire process is conducted in a ISO registered facility. Best of all, since the manufacturing process is so carefully controlled, durability is assured.
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. These converters are made in a highly controlled and repeatable manner to duplicate the performance of the OEM models.

What is the concept and operation of ultrasonic vibrator and power supply matching?
Let the transducer and the driving power supply and the welding mold cooperate well to form a complete ultrasonic device, which is simply referred to as matching. Since the impact of matching on the performance of the whole machine is decisive, the importance of matching is not overemphasized. The primary consideration for matching is the capacitance of the transducer, followed by the frequency of the transducer.
It should be emphasized that the ultrasonic transducer itself is not an energy generator, it is just an energy converter. It converts electrical energy into acoustic energy (mechanical energy), which can convert (output) a large amount of energy on the premise that the input (drive power) and output (amplifier, mold) are well matched.
Input matching refers to the matching of the transducer and the driving power supply. If the output is well matched and the input matching is not good, the transducer is weak and the welding is not strong. If the output is not well matched and the input is well matched, the transducer will be overloaded, causing the wafer to be misaligned, broken, broken, broken, or burned. For example, just like a car slamming on the throttle in a neutral state, the engine is definitely vulnerable.
