【NEW】Weld tester (handheld type): MM-410A.MM-315B

"Visually" control for better weld quality.
Model : MM-410A MM-315B

[ MM-410A ]

For Better Quality Control of Resistance Welding !
Measures current, voltage, welding time, weld force. It is a handheld type which is convenient to carry.

  • Improve measurement accuracy
    RMS which is compliant ISO17657 is available for all measurement conditions by adopting ISO17657 compliant toroidal coil.*
    It can be also selected the arithmetic mean RMS which is a conventional calculation system.
    *: By using MB-400M/MB-800M
  • Various measurement functions
    Up to 10 measured values which are important to judge welding quality can be displayed and judged.
    Also, 4 waveforms can be displayed. Easy setting through the menu selection system on the 5.7-inch color touch panel.

  • Display screen


    • User friendly OK/NG judgement

      Result of OK/NG judgement is displayed on the screen. Using condition numbers, operator is able to see the result by checking the screen.

    • Supports a wide range of welding machines

      The instrument supports single-phase AC, DC inverter, AC inverter, transistor, and capacitive discharge welding machines.

    • Supports multiple languages

      Languages available are Japanese, English, Chinese, Korean, German, French, and Spanish.

    New Features

    • AC/DC seam measurement mode

      Up to 5 minutes of moving measurement (Measures current/voltage in AC welding or voltage in DC welding )

    Memory / Communication

    • Memory

      You can store measured values and waveforms in USB or built-in flash memory.

    • Communication

      USB, Ethernet(TCP/IP) Simplex and duplex communication possible.

    Expand function

    • With external input function, voltage input (± 10 V) current input (4 to 20 mA) from other sensors such as temperature sensor can be measured, waveform display, and OK/NG judge possible.
      * Judgment can not be output.
