Click the ultrasonic testing button for short time, observe the indicated value of the
degree of frequency deviation (frequency deviation protection will occur when the
degree of frequency deviation exceeds 20%); adjust the frequency-adjusting knob
finely to raise or lower the working frequency band, and then click the ultrasonic
testing button, observe if the indicated value of the degree of frequency deviation
is lower than the previous value; if lower, continue to adjust the
frequency-adjusting knob in the previous direction, and simultaneously, click the
ultrasonic testing button in short time, observe the indicated value of the degree of
frequency deviation until the degree of frequency deviation is adjusted to the
minimum (less than 10%). If higher than the previous value, adjust the
frequency-adjusting knob in reverse direction, and simultaneously, click the
ultrasonic testing button in short time, observe the changes in the degree of
frequency deviation until the degree of frequency deviation is adjusted to the
minimum.

Notes for the adjustment:
a. The minimum degree of frequency deviation (less than 10%) and the
minimum no load (less than 0.5A) are the standards for frequency control.
b. In case of errors with transducer system or serious frequency deviation for
connection failure or misconnection of transducer, it will not work to correct
frequency now. The transducer and connecting wires will have to be adjusted
or replaced.
c. In special unexpected cases such as replacing or repairing the components of
transducer (like acoustic welding head), the occurrence of frequency deviation
protection during operation, and the first time of switching on and operation, it
requires calibrating the working frequency band of the generator.
2) Load parameters
KCH series hand-type ultrasonic welding machine can adjust load parameters
automatically according to the load. Under normal status, the load under no load is the
lowest (less than 0.5A), and the load is related to the factors like the welded work
piece and the welding pressure in the process of welding. Over high load may result in
overload protection. Some models can limit the load automatically.
