Claims

[Scope of utility model registration request]

The electrode tip of the spot welder is fitted directly to the tip of the gun arm, and the electrode tip of the spot welding machine is used for spot welding such as white bodies in difficult places where it is difficult to insert the gun arm. A spot comprising a formed base and a head offset from the base toward the tip of the gun arm, and a ring-shaped groove is carved in the center of the outer periphery of the base to communicate with a cooling water path buried in the gun arm. Special electrode structure in welding machines.
