Claims (1)

[Scope of Claim for Utility Model Registration] (1) An earth plate placed around the stud to be welded loaded at the tip of the welding gun and carried by the welding gun so as to be able to press the base metal in the vertical direction. Equipped with a stud welding jig. (2) The welding gun is equipped with grounding rods arranged at equal intervals around the studs to be welded loaded at the tip of the welding gun and attached to the welding gun so as to be perpendicular to the base metal. A stud welding jig in which the verticality of the rod relative to the base metal can be maintained by a height adjustment rod.
