Ultrasonic power supply with Distance model flexible automobile bottom guard welding

Parameter:

Power Supply. Every ultrasonic welder starts with a power supply. The power supply is sometimes referred to as the frequency generator because it takes standard electrical power (usually 115V/220V) at 60 Hz and converts it to the operating frequency of approximately 20 kHz or 20,000 cycles per second. Other output frequencies commonly available range from 15-70 kHz. This high frequency current is then sent through a special cable to the ultrasonic stack.

When investigating ways to join plastic parts, you will almost certainly settle on a process that falls into one of these categories: mechanical, adhesives, or welding. Mechanical processes such as snap-fit, screws, or rivets are great if the product needs to be disassembled during its life or if the product will be run in low volume. Adhesives like glue form a more permanent bond and excel at adhering two dissimilar materials. Plastic welding processes are permanent in nature, have no consumables, and use a combination of heat and pressure to fuse the parts together. One particular welding method should not be overlooked when evaluating manufacturing methods: ultrasonic welding.

Advantage :

• Trigger by Power patented feature provides the ability to accurately start the weld process once a programmed force is achieved. Combined with Weld by Energy, this unit delivers the highest level of process repeatability of any probe system available today.
• Time, energy ,depth , Multiple combined welding weld modes.
• Amplitude adjustment in 1% increments from 90% to 10%.
• Eight programmable setups.
• Power bar graph with last cycle memory.
• High-resolution multicolor LCD with a multilingual menu for quick, easy programming.
• Real time in cycle menu displays frequency, power, and time.
• 100% digital controls of all power supply functions and parameters.
• Digi-Trac tuning automatically tracks the resonant frequency digitally. It adjusts the output frequency to match the acoustic stack. This is done for every weld cycle and eliminates the need to manually tune the generator.
• Ultrasonic overload protection, with fault indication for ease of troubleshooting. The overload power limit is based on true RMS power output level.
• Patented pulse-width modulation design delivers power more efficiently with substantially less stress on electrical components for superior performance, reliability, and extended life
