MM-400A desktop resistance weld checker monitors welding variables that result in changes in weld heat, including current, voltage, time, force and displacement.

Supports AC, DC inverter, AC inverter, transistor and capacitive discharge resistance welding technologies. Is reportedly ideal for use in process development; can be used to correlate waveform and numeric data with process results and provide detailed weld data for process optimization and validation. Reduces scrap by detecting drifts in weld process and alerting operators before process failure. Reduces frequency of destructive testing and provides monitoring of welding power supply. Features intuitive user interface and color touch panel display. Envelope function sets upper and lower segmented or continuous limits around waveform. Seam welding mode monitors AC current and voltage or DC voltage for up to 5 min. Provides ISO17657-compliant measurement for current (when used with available ISO-compliant toroidal coil). Offers Ethernet (TCP/IP) and RS-232/485 communication.
