The utility model discloses centralized control explosion-proof equipment for an arc welding power supply. Arc welding power box, a shell of the arc welding power box is of a closed box body structure. A first air inlet and a second air inlet are formed in the side face of a shell of the arc welding power box at intervals. An air outlet is formed in the top face of a shell of the arc welding powerbox. Through switching of the three-way air valve, the heat dissipation air inlet mode of the arc welding power box can be changed; the main air inlet pipe dissipates heat by adopting common air; airentering through the secondary air inlet pipe is deoxygenized through the deoxygenization box, so that the oxygen content can be reduced; the deflagration condition of electrical equipment can be reduced by reducing the oxygen content, meanwhile, the sponge iron can be repeatedly utilized, so that the sponge iron is relatively more environment-friendly, low dust and low oxygen content of the whole body are realized by mat
