The invention relates to the technical field of welding equipment, in particular to a welding gun protection device and welding equipment. The welding gun protection device comprises a shell, an elastic part, a trigger part and a plurality of trigger switches. The shell is connected with a welding gun; the triggering part comprises an abutting part and a connecting part, the abutting part is located in the shell, and the connecting part penetrates out of the shell; the trigger switches are installed on the shell and arranged in the circumferential direction of the abutting part at intervals; one end of the elastic part is connected with the shell, the other end of the elastic part abuts against the abutting part so that the abutting part can abut against the trigger switches, the elastic part can deform in any direction so as to drive the shell to swing relative to the trigger part, and therefore the at least one trigger switch can be far away from the abutting part. When a gun head is collided, the elastic part deforms to drive the shell to move relative to the trigger part, the attaching state between the trigger part and the trigger switches in different directions is changed, and protection programs of an alarm device and the welding equipment can be triggered in all directions, so that multi-direction protection on the gun head is achieved.
