Amada Weld Tech announces MM-410A handheld resistance weld checker

AMADA Weld Tech, a manufacturer of equipment and systems for resistance welding, laser welding, laser marking, laser cutting, laser micromachining, and hot bar bonding, has announced the new MM-410A handheld resistance weld checker. The compact unit supports a wide range of resistance welding technologies including AC, DC inverter, AC inverter, transistor, and capacitive discharge. Featuring a simple and intuitive user interface and colour touch panel display, the MM-410A provides information on current, voltage, weld time and force and is ideal for use in process troubleshooting, where it can be used to correlate waveform and numeric data with process results and provide detailed weld data for process optimisation and validation.

The unit provides ISO17657-compliant measurement for current (when used with available ISO-compliant toroidal coil). It offers easy set up using the 5.7" colour touch panel. The unique seam welding mode monitors AC current and voltage or DC voltage for up to five minutes. Data storage is available using an onboard flash drive. The MM-410A offers Ethernet (TCP/IP) and RS-232/485 communication. Multi- language support includes English, Spanish, Japanese, Chinese, Korean, German and French. Available accessories for the MM-410A handheld resistance weld tester include toroidal coils, force sensors and current/force sensors. Amada Weld Tech www.amadaweldtech.com

If used continuously in a production environment it reduces scrap by detecting drifts in the weld process and alerting operators before process failure. The MM-410A also reduces the frequency of destructive testing and provides an independent way of monitoring the welding power supply by detecting any drifts in welding power supply calibration.
