The inclusions reduce the mechanical properties and corrosion resistance of the parts, affecting the production quality of the device. The guide column cooperates with the cleaning brush to clean up the debris still attached to the welding wire after grinding with the grinding belts 1 and 2, so that the impurities attached to the welding wire can fall smoothly into the bottom of the rotating tube, and cooperate with the rotation of the rotating tube so that the fallen impurities are centrifugally acted and collected in the slot, which is beneficial to prevent the impurities cleaned up from scattering when the rotating tube moves and rotates with the arc generator body, causing the impurities to be adsorbed on the welding wire again or fall on the product, affecting the production effect of the device.

[0018] 2. Through the stirring column that is set, the chain drives the stirring column to slightly stir the molten pool after the arc generator body is fused, which is beneficial for the device to accelerate the discharge of gas in the molten pool and prevent the molten pool from containing hydrogen and other gases, which will cause pores in the molten pool during the cooling process and affect the production quality of the device. The rotating plate with stirring columns of different positions and sizes can also be replaced to help the device adapt to different production needs and improve the convenience of the device.

[0019] 3. Through the top box that is set up, the protective gas is evenly and vertically blown toward the placement block, which is conducive to the formation of a shielding layer for the protective gas to block external impurities and moisture in the air from entering the molten pool, thereby reducing the generation of impurities and pores. At the same time, the protective gas evenly and vertically blown toward the placement block is conducive to preventing the arc generated by the device from being unstable, affecting the transition of the molten droplets and the solidification process of the molten pool, and reducing the mechanical properties and surface quality of the parts. The heating wire heats the gas and dries the welding wire passing through the heating tube, which is conducive to preventing the moisture attached to the welding wire from decomposing under the action of the high-temperature arc to produce hydrogen that dissolves in the molten pool and precipitates during the cooling process to form hydrogen pores, resulting in reduced mechanical properties and fatigue resistance of the parts, affecting the production quality of the device.
