Ultrasonic Welder

• Model : MT-3015, 2020AC

Wide range automatic tuning system

• 15 KHz ± 350 Hz
• 20 KHz ± 500 Hz
• 30 KHz ± 700 Hz
  Maintaining an optimized condition with tracking the change of frequency caused by wearing tool horn and increasing temperature while tool horn working.

Saving working frequency & displaying actual frequency

• It is available to keep the optimized condition oscillating with the saved frequency after welding. And displaying the actual frequency makes easy to check and manage the converter.

AVR function built-in

• Constant amplitude is maintained regardless the input voltage change of 180 ~ 260 Volt.
  (In general model, there is amplitude fluctuation of ± 10%, in case of input power change of ± 2%)

2 steps constant amplitude function

• Keeping constant amplitude with 2 steps amplification function of generator applied FET or IGBT and AVR device regardless loading condition.

The most advanced digital generato

• The digital type generator is able to control precisely regardless environment variation or component error.
  (Applying 3 pieces of EPLD and 5 pieces of CPU)

Digital type soft start and adjustment of 8 steps power raising speed

• Supplying the output almost linearly rather than steps prevents the damage on the tool horn and generator, which may happen due to the shock wave while oscillating the ultrasonic initially. It is available to adjust the starting output speed to eight (8) steps depending on the tool horn size and welding product condition.
  [Example : for large tool horn at 150ms and low pressure-high output welding at 50ms starting velocity]

Electronic amplitude adjustment function (10~ 100%)

• Providing an easy adjustment for amplitude by a switch without changing the main horn and a optimum welding condition according to welding material and product condition.

Precise overload protection device

• Protecting completely the damage on generator and main horn through checking current, voltage, phase and frequency.

Low pressure - high power welding function

• Applicable to precise welding with complicated product and material because it is available to reach a maximum power within 0.05 second at low pressure in order to prevent scratch and product damage.

The most advanced digital control device

• Displaying various welding condition and information, controlling the welding time at 0.01 unit.

Momory for welding conditions

• Available to save and read up to 10 memory welding condition, which makes easy for applying to various welding products.

Self-chech for good or bad welding quality

• Welding quality control to check good or bad welding quality by itself according to the setting value range in energy mode or time mode while welding.

Alarm function

• Displaying various messages including machine malfunction, bad welding quality on the LCD screen.

2 Steps pressurization function, (not applied to 30KHz)

• Improving the welding strength and productivity and minimizing the inferior welding for crystalline materials such as Nylon and Acetyl.

2 Steps amplitude function

• Contributing to precise welding operation and improving the welding strength for non-crystalline materials such as ABS and Acryl.

Application for additional pneumatic jig and transfer jig.

• Equipping the control device for external pneumatic equipment (fixing clamp, transfer jig and soundproof door) in the control unit.
