Displacement value can be read in both + (plus) indication and – (minus) indication.
- ◆Supports various types of welders.
Supports single-phase AC welders, DC inverter welders, AC inverter welders, and transistor type welders.
- ◆Simple operation with a dial
Turn the dial to scroll the screen, move the cursor, and select items. Press the dial to select the item where the cursor is located.
- ◆Clear display of the current and voltage
320x240 dots/4.7-inch color LCD screen.
- ◆Various display capability
Displays various welding waveforms without using an oscilloscope.
- ◆Waveform re-display feature (FIT feature)
The displayed waveform can be shifted and zoomed in and out in the screen. Even if the waveform of where you would like to observe went off the screen, it can be back to display the waveform again. (Pat. Pend)
- ◆Supports multiple languages
You can select the language from Japanese, English, Chinese, Korean, German, French, and Spanish.
- ◆Recording and transferring of data
- The measured values and waveforms can be saved in a memory or transferred out to PC for analysis.
- Data transfer can be done in the RS-232C to PC.
- Data can be printed out by the local printer equipped with the device.
- ◆Options◆Display screen
- The applied force and weld current can be measured simultaneously while welding (Optional weld thru sensor, MA-770A or MA-771A is necessary).
- Voltage signal (Max.±10V) from other sensor can also be measured due to the external input facility.
-
- ◆Accessories
[ MM-122A ]
Highly functional and highly precise weld monitor (checker) for various weld current waveforms.
- ◆Cyclical and accurate display of the welding time for AC inverter welding.
- ◆Light and compact body. Fast measuring speed, and easy installation.
- ◆Simple "turn" and "press" operations with a single button.
- ◆The measuring unit from "ms" or "Cycle" on measuring welding time can be selected.
- ◆Communication facility is equipped on standard.
Measured values can be transferred to a PC and the evaluation criteria can be changed from the PC. RS232C and RS-485 are equipped on standard
[ WM-A728 (Weld checker dedicated to PULSETIG welding) ]
