At the same time, the blower 82 is started through the main console 10. Wind blows from the blower 82 into the exhaust duct 83. The exhaust duct 83 brings the wind into the liquid cooling box 84 to enhance the heat dissipation effect. At the same time, the wind comes out from the telescopic pipe 85 to the air outlet 87 to cool the welded part, reducing the possibility of deformation of the welded part, improving the welding quality, enhancing the material performance, and increasing stability and safety. When the moving plate 61 moves downward, the circumferential surface of the second pulley 810 contacts the circumferential surface of the second convex block 811 to generate friction and drive the second pulley 810 to rotate. The second pulley 810 drives the connecting shaft three 88 to rotate, and the connecting shaft three 88 drives the cross plate 89 to rotate to stir the coolant in the liquid cooling box 84, increasing the contact area between the coolant and the surface to be cooled, enhancing the heat exchange rate, thus accelerating the cooling process, avoiding sediment accumulation, and improving the cooling effect.
