Ultrasonic Handheld Welder HW-D Series

Ultrasonic Handheld Welder HW-D Series

The HW-D series is equipped with peak power mode, energy control mode, general timer control mode, and a continuous oscillation mode, all of which are suitable for resin caulking.
The welding result display function makes it easy to check the welding conditions of new products as well as to check when there is a welding failure.

This compact ultrasonic spot welder can be used not only for hand-held work, but also for preventing poka yoke(fool-proofing), connecting to a shot counter, and installing on an automatic machine.

  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.
  1. Supports minute work (60kHz)

    Quick welding start contributes productivity improvement.
    Suppress buckling of small size boss to contribute to higher yield.
  1. Welding result display
    Frequency, Oscillation time, Energy, Peak power
  1. External output of welding results
  2. Variable amplitude function (30 to 100%)
