Weld Monitoring

With increased emphasis on accountability and traceability of resistance welding processes comes the need for process monitoring and enhanced process control. To complement the MACGREGOR range of resistance and micro arc welding equipment, MacGregor Welding Systems offers weld monitors that suit most applications and close the quality loop in your process. 

Weld Monitoring offers the tools required for process development, production monitoring, data collection and analysis to support your quality system requirements.

Our four parameters for monitoring:

  1. Welding current
  2. Welding voltage
  3. Electrode penetration
  4. Electrode force


For many relatively simple processes, for example the welding of ferrous metals, control of absolute limit values for current and voltage suffices completely. For critical bonds such as certain bonds of copper alloys, however, increased monitoring is necessary. In this case, too, the four parameters named above are monitored, not only within fixed limits, but also within envelope waveforms, among others.

Weld Monitoring Benefits

MacGregor Welding Systems offers weld monitoring devices, reliable and robust units which offer to store and to transfer data conveniently. The high-end versions have sophisticated and intuitive multilingual software. For more details, please consult the related products section below.
