Handheld welder which contributes to welding quality improvement
and shortening of tact time will be released.
Nippon Avionics Co., Ltd. (Avio) (Headquarters: Yokohama-shi, Kanagawa. President: Mr.
TAKEUCHI, Masato) will release【HW-D series, Ultrasonic Handheld Welder】for which oscillation
mode can be selected for different applications and incorporation into an automated system can bemade in addition to manual operation.
In information devices and automobile industries, percentage of electronics in hardware isincreasing constantly. As the hardware becomes more functional and components are miniaturized,manufacturing is becoming difficult, and manufacturing (or MONOZUKURI) with higher reliability is
becoming extremely important. The product being released this time realizes stable welding, withthe fastest speed among the handheld welders from Avio, and rich welding control functions arefurther improved. Furthermore, external interface features, strengthened comparing to our previousmodels, make this product compatible to automated systems, and it will contribute to manufacturingof high quality products in various manufacturing shops.
This time, 2 series (total 5 models), namely the standard model and the high-end model for world
market based on multiple power supplies, will be released. High frequency model (60kHz,maximum output of 200W) is included in the series for the first time for Avio. This model is capableof welding fine boss or crimping of plastic rib which was difficult with the conventional ultrasonicwelders. As a result, optimum welding capability is offered for various applications.

Ultrasonic Handheld Welder【HW-D Series】

Major features:
1. Production tact time is shortened by high speed welding.
Digital ATHMOS (*) control is equipped. Fast rise time, which is one of the features of Avio
ultrasonic welder, enables fast rise even when the pressure is applied, and amplitude with the least
loss realizes high speed welding.

*Digital ATHMOS control
ATHMOS (Automatic Tuning Hold Master Oscillator System), which is Avio proprietary ultrasonicoscillation frequency automatic tracking system, and digital circuits are combined. Whilemaintaining high speed welding, which has been Avio’s traditional feature, stability and multifunction are realized by digitalization.
2. Optimum welding is realized by selection of oscillation control mode.
As oscillation control function, 4 oscillation control modes are available, namely peak power
control, energy control, and continuous oscillation in addition to the conventional timer control.
Optimum mode can be selected as desired depending on the work shape, size and specification
for finish.

Example: plastic crimping, peak power control
By auto control of the peak power (a type of control where the oscillation is stopped when thepower reaches the preset level as a result of sudden power (W) increase due to the increase ofload resistance against ultrasonic oscillation when the boss is fully crushed), stable crimping
quality can be obtained.
3. Rich interfaces contribute to automation and production control.
In addition to oscillation control by external signal, signal for oscillation on and oscillation end canbe sent out. Furthermore, analog output is available for voltage, current and power, which is usefulfor production control and quality control.

4. High frequency/high output model is useful for miniature works.
A high frequency/high output model (60KHz frequency and 200W output) is offered to cope withwelding of small boss or rib of φ2mm which used to be difficult to weld by conventional ultrasonicwelding due to deformation or bending. Crimping of high strength can be realized by welding timeof approximately one half comparing to the time required for heat crimping.

High frequency

Low frequency

Yield ratio can be improved by suppressing deformation or bending of thin diameter boss.
Weld start is faster because of the least loss of amplitude, and it contributes to productivity
improvement.
