The invention discloses welding machine equipment and a voltage calibration method and device thereof. The voltage calibration method comprises the steps that a set voltage value and a first initial relation are obtained; according to the first initial relation, the set voltage value is converted into a first digital signal, and the first digital signal is output to the voltage control system; acquiring an actual voltage value of the load unit; judging whether the actual voltage value is equal to a set voltage value; if yes, storing the current first digital signal; the first digital signal and the actual voltage value form a first coordinate; adjusting the set voltage value according to a second preset rule, and returning to execute the step according to the first initial relationship until a preset number of first coordinates are obtained; and determining a first calibration relationship according to the preset number of first coordinates. By adopting the scheme, the voltage calibration can be realized quic
