With increased emphasis on accountability, the MG3 Digital Process Sentry offers the tools required for process development, production monitoring, data collection, and analysis to support your ISO, GMP and TQM requirements. The MG3 represents the very latest technology in resistance weld monitoring; it provides precision real-time dynamic measurement of all the welding variables and is an invaluable tool for: Process Development Welding Evaluation and Research, DoE Studies, Process Optimization, Process Validation Process Monitoring Data Logging, Setting Process Limits, Electrode Maintenance,Troubleshooting, Set-up Verification, Statistical Process Control Quality Control Traceability, Process Certification and Analysis, Calibration Confirmation, Statistical Process Control With three models to choose from, the MG3 can monitor up to two simultaneous channels of current and voltage from up to two AC, DC or CD power supplies for spot or seam welding. In addition to the basic model, the W1 and W2 models have single and dual channel displacement capability, respectively, and also offer inputs for force and pressure sensors. Upper and lower limits can be set to trigger alarms for all measurements; for more advanced users, these limits can be set as envelopes that follow the contour of the waveform. Judgment of good/bad welds can be determined by status LED’s on the front panel and outputs from the MG3’s I/O. All welding parameters are stored in internal memory, available from the built-in RS-232 port, and data may be transferred to a Compact Flash (CF) card and directly exported into Excel® for user-defined analysis. The MG3 also has a convenient “SNAPSHOT” feature to save screenshots for reports. Comprehensive SPC functions include run chart logging and histograms. weld monitoring MG3 Digital Process Sentry • Measure voltage, current, force and displacement • Dual channel capability • Configurable user interface with four display quadrants • Full on-screen SPC capability • 99 available schedules with password protection • Serial output via RS-232 • Weld interrupt function

2 The high resolution color display and user configurable run screen enables users to configure the display to show information relevant to their particular job function or chosen welding environment.Two-channel capability allows simultaneous measurement and comparison of two welding systems. The MG3 is easy to program via a single rotary encoder knob. Up to 100 monitoring programs can be stored for multiple parameters.
