MM-380A Portable Weld Checker

Features and Benefits

Measures weld current, voltage, time and force
Weld thru Sensor
Easy to read 5" Screen and s Menu navigation
Intuitive Waveform graphic analysis of data
External Printer and RS232 output

The hand-held MM-380 is designed to provide quick, precise and comprehensive measurements of the welding process. The MM-380 utilizes a weld through sensor measures current, voltage and force simultaneously between the electrodes. The 5” color display provides precise graphical displays of waveform time and amplitude, in addition to numeric peak and average values. Measurement setup, waveform analysis and menu navigation is very straightforward, and achieved using a rotary encoder. Waveforms and data can be output through an optional in printer or via COM port for screen capture and data collection.

The MM-380A uses either the MA770 or the MA771 weld thru sensors:
