Ultrasonic Handheld Welder HW-D Series

Support reliable “Monozukuri” (manufacturing) Handheld model which contributes to shorten processing time and quality improvement!

HW-D series realizes stable welding at high speed. In addition to selecting the most suitable control mode for the work, welding control is also enhanced.
Furthermore, it is a hand-held type ultrasonic welder that can be linked with external equipment.

  • Digital oscillation tracking function
  • Selectable oscillation control mode
  • Welding result display / Error code display
  • Many Interfaces
  • High power 60kHz for fine work


1.Peak power control mode equipped

When a boss is completely crushed in process of plastic caulking, load resistance to ultrasonic vibration increases, which makes sharp increase of power (W). Stable caulking quality can be obtained by controlling to stop oscillation when specified power is reached.

2. Supports minute work (60kHz)

Quick welding start contributes productivity improvement
Suppress buckling of small size boss to contribute to higher yield.
