【NEW】WELD CHECKER® MM-400B
[ MM-400B ]
Measures current, voltage, welding time, weld force and displacement!
- ◆Supports a wide range of welding machines
The instrument supports single-phase AC, DC inverter, AC inverter, transistor, and capacitive discharge welding machines. - ◆Various measurement functions
Easy to use with a touch panel.Display waveforme up to 4 items. Display and judge the parameters of the welding quality determinant up to 10 items. - Display screen
- ◆ISO17657-compliant measurement
In addition to the arithmetic mean RMS which is a conventional calculation system, the RMS in a whole current flow time which is the ISO17657（Resistance welding -- Welding current measurement for resistance welding -- ）-compliant calculation system can be selected. For the ISO17657-compliant measurement, the dedicated ISO-compliant toroidal coil is required.
- ◆Supports multiple languages
Languages available are Japanese, English, Chinese, Korean, German, French, and Spanish.
[ New Features ]
- ◆Envelope function
Making the OK/NG judgment by comparing a waveform within an allowable range and a monitored waveform, enables management with waveforms in addition to conventional measured values.
(Up to 3 points 2 waveforms)
- ◆Measurement with seam current
Measures current/voltage in AC welding or voltage in DC welding with a max. 5-minute moving measurement.
- ◆Measuring displacement Before-Welding
Measures Before-welding workpiece thickness, judge OK/NG of thickness.
[ Memory / Comumication / Printing ]
- ◆Memory
Measured values and waveforms can be saved in a built-in flash memory device/external USB.
- ◆Comunication
RS-232C, RS-485, Ethernet(TCP/IP) Simplex and duplex communication possible.(option)
- ◆Printing
Measured data and wavefome can be printing.
[ Judgment / Control function ]
- ◆By using a built-in force sensor / displacement sensor, it is possible to measure changes in pressurizing force / displacement amount even during production, display waveforms, judge OK/NG of welding.
- ◆Weld stop function shifted from 2 outputs to 3 outputs. Fine control of changes in displacement and applied pressure during welding.
- ◆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.
