  • Solution Secondary Current Calibration

  • 9180 Controls with SC Software
    SOLUTION controls are factory calibrated to match a Unitrol Standard. Unfortunately there is no practical traceable U.S. standard for calibration of non-sinusoidal AC current produced by a resistance welding machine. This document will allow you to use the special calibration feature included in this series control to match a separate or standalone weld checker. (Secondary Current Cal.pdf)
