Installation and Commissioning
1. Installation of the equipment
1) The equipment should be installed on the solid table board, with a space of 150mm
in the rear.
2) Power supply should meet the requirements of equipment operating technical
parameters, unstable voltage will exert direct influence on the welding effect, or in an
even more serious case, result in shortening service life of power generator or burning
it! Areas with unstable voltage require a voltage stabilizer with fluctuation of output
voltage below 2% and the output power double the nominal power of the welder.
3) There is no fire source, well-ventilated, stable installing.
4) Before operating the welder, make sure to connect the ground wire properly, with
ground resistance less than 0.5ohm.
Never operate the welder without proper grounding!
5) Before switching on, please make sure that proper power supply and air supply are
used, the cable wires have been connected correctly, the limit of welding head has
been well set, and the hands and other parts are at safe operation position.
2. Commissioning the operational parameters
1) Parameters of working frequency
The power generator of KCH series hand-type ultrasonic welding machine can track
the working frequency of the transducer automatically within certain range of working
frequency (i.e. working frequency band). However, influenced by external factors,
changes of the transducer’s natural frequency may exceed the generator’s working
frequency band, which may lead to the fault of frequency deviation. Operating the
welder under the status of frequency deviation will cause poor welding quality, or more
seriously damage the ultrasonic power generator or transducer system. Therefore, in
the event of frequency deviation, make sure to calibrate it.
z
Phenomena of faults of frequency deviation:
a. The degree of frequency deviation is too high, and frequency deviation
protection occurs.
b. No load output current is very high, or even overload protection occurs.
c. The welding head squeals, with serious heating up.
