Amada Weld Tech’s MM-400A desktop resistance weld checker monitors, manages key welding variables

Amada Weld Tech 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 unit is suitable for use in process development, where it can correlate waveform and numeric data with process results and provide detailed weld data for process optimization and validation. In a production environment, it reduces scrap by detecting drifts in the weld process and alerting operators before process failure. The machine also reduces the frequency of destructive testing and provides an independent way of monitoring the welding power supply.
