MM-123A Weld Checker

The MM-123A is the very latest in stand-alone weld checker technology. This multi-functional weld checker comes in small, compact design.

The MM-123A now features voltage monitoring. This allows you to monitor important variable for quality control.

The MM-122A uses a Toroidal coil for sensing. The correct coil needs to be matched to your application – MB-400M/MB-800M.

Measures Single Phase AC, DC Inverter, AC Inverter, Capacitor Discharge, Transistor
Newly Added – Voltage Monitoring
- Allows you to monitor voltage & current at the same time
Improved measuring precision
- Enables to measure the RMS based on ISO 17657 without any exceptions
Upper/Lower limit judgement
- Detection of errors that can occur welding problems is available
Long time measuring
- Available for measuring in 3000ms, and this feature is suitable not only for spot welding but also fusing
Communication
- The new product offers Ethernet (TCP/IP) and it enables one-way/two-way communication
- Uniform management at lap top is available by transmitting the monitor data or error data
- The two-way communication implements input/output of schedule data
