The utility model relates to a machine head of a multi-wire submerged arc welding machine. The machine head comprises an installing plate, a machine head installing frame, a soldering flux storage box, an upper limiting protective device, a left and right adjusting mechanism, an upper and lower adjusting mechanism, a camera, a cross cursor component and a screw adjusting mechanism component, wherein the installing plate, the soldering flux storage box, the upper limiting protective device, the left and right adjusting mechanism, the upper and lower adjusting mechanism, the camera, the cross cursor component and the screw adjusting mechanism component are arranged on the machine head installing frame; the camera and the cross cursor component are connected with a control cabinet through data lines; and the control cabinet is connected with a displayer which is arranged on an operating platform. The machine head has the advantages that the distance between welding guns can be adjusted in the lengthways direction and transverse direction, and the angle of each welding gun can also be adjusted in the lengthways direction and transverse direction, thereby the welding technology is optimized; simultaneously the camera is convenient for an operator to observe the condition of the machine head and adjusting alignment and other welding requirements; the efficiency of welding production is improved; and the working efficiency of the operator is reduced.
