Dynamic Force and Amplitude Control™

with Multi-Step Welding

  • Capability of over 20 weld steps with unique force and amplitude parameters.
  • Ability to change and adjust force and amplitude during the weld cycle to optimize welding parameters for each specific wire application
  • Energy and frequency remain constant

Load Cell Force Feedback

Under 10µm Resolution

  • Consistent measurement and ultrasonic output produce high cPk values
  • Measurement of pre-weld and post-weld height and width
  • Cross section area measurement and calculation for additional quality control

The US-935S, developed by TECH-SONIC, is the lower power version of the US-3020S.

The US-3020S allows for absolute control of weld force and travel distance by utilizing a servo actuated mechanism and force feedback sensing. Utilize this machine for more delicate applications such as solar panels, ceramic-based circuit boards, and small metal parts.
