Amada Miyachi America’s MM-400A desktop resistance weld checker monitors key welding variables

Amada Miyachi America has introduced the MM-400A desktop resistance weld checker. It allows operators to monitor and manage key welding variables that result in changes in weld heat, including current, voltage, time, force, and displacement. The compact unit supports AC, DC inverter, AC inverter, transistor, and capacitive discharge resistance welding technologies.

The weld checker is suitable for use in process development, where it can be used to correlate waveform and numeric data with process results and provide detailed weld data for process optimization and validation. In a production environment, it can detect drifts in the weld process and alert operators before process failure.
