The invention relates to the technical field of welding equipment manufacturing, in particular to a four-welding-gun press-fitting electric welding machine. The four-welding-gun press-fitting electric welding machine comprises a fixing frame, four main welding guns and a mounting base. The fixing frame comprises an electric welding box, an object carrier, a rotary table and a lifting platform, and the object carrier is mounted in the middle of the electric welding box; the rotary table is mounted on the object carrier; the lifting platform is mounted at the center of the rotary table; and the main welding guns are mounted on the mounting base. According to the four-welding-gun press-fitting electric welding machine, two kinds of pluralities of welding guns are arranged, the main welding guns and auxiliary welding guns both can be subjected to front and back position adjusting and angle changing, and the installation center lines of the four main welding guns are intersected at a point, the same position of an object can be welded simultaneously, the deformation caused by welding of a single welding gun can be effectively reduced, the structure is simple, the efficiency is guaranteed, and further the welding deformation is reduced.
