Beschreibung
Zusammenfassung:	The utility model discloses a welding argon filling device which comprises a gas supply hose, a needle tube, a valve and a fixing mechanism, one end of the gas supply hose is connected with a gas source, the other end of the gas supply hose is connected with the needle tube, the valve is arranged on the gas supply hose, the gas supply hose is connected with the fixing mechanism, one end of the needle tube is connected with the gas supply hose, and the other end of the needle tube is connected with the fixing mechanism. The other end of the needle tube is a closed end, and air holes are formed in the two opposite sides of the closed end. During welding operation, the closed end is inserted between the first welding piece and the second welding piece, argon in the needle tube is sprayed out towards the first welding piece and the second welding piece through the air holes in the two sides, the argon blown out of the two sides of the needle tube can be soft and uniform in a two-way air outlet mode, the argon fil
