MM-380A – Handheld Weld Checker

Hand-held weld checkers have been designed to provide quick, precise and comprehensive measurements of the welding process. The MM-380A weld checker utilises a weld through sensor and measures current, voltage and force simultaneously between the electrodes.

This weld checker also features a 5” color display, which 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.


  • Measures current, voltage, time and force
  • Weld thru sensor
  • Easy screen menu navigation
  • Intuitive waveform and data analysis
  • External printer and RS232 output
