Stay in compliance with welder calibration. Our field personnel come to your facility to verify the calibration on ammeters and voltmeters on your welding equipment and provide reference measurement of wire feed speed and shielding gas flow rate (optional service.) 

  • Amperage and voltage equipment verified against calibration requirements and traceable to NIST

  • Wire feed speed and shield gas flow rates measured and recorded (optional, for reference only)

  • Complete reporting by machine including machine identification & description, testing settings, measured readings, allowed deviation, measured deviation, as-found/as-left and satisfactory/unsatisfactory indication
