To increase the efficiency of welding equipment calibration, verification and validation, ESAB has introduced the Checkmaster 600R resistive load bank for simulating GMAW, AC/DC GTAW, SMAW and SAW arc welding processes from 150 to 600 amps. When linked with the ESAB WeldScanner multipurpose recording and measuring device, minimal user intervention is needed for calibration and validation, leading to time efficiency. Integration with the WeldScanner allows parallel operation of three Checkmaster 600R units, automatically switching resistive loads simultaneously.
