Beschreibung
Zusammenfassung:	The lower electrode of the fixed welding machine comprises an electrode body, a positioning groove is formed in the upper end face of the electrode body, a positioning mechanism is arranged in the positioning groove, the positioning mechanism comprises a positioning core and a cover cap, the cover cap is connected to a groove opening of the positioning groove in a threaded mode, the positioning core comprises a positioning head, a positioning pin and a tail plate, and the positioning head is connected with the positioning pin. The bottom of the positioning groove is provided with an air blowing hole communicated with the outside. The lower electrode has the advantages that the lower electrode is used on a fixed welding machine, the air blowing opening is formed in the bottom of the positioning groove, air is introduced, and no sealing mechanism is arranged between the positioning pin and the cover cap, so that air flows out from the position between the positioning pin and the cover cap to blow slag to a nut
