PURPOSE: A jig apparatus of a resistance spot welding machine is provided to protect a worker from current flowing during welding or remaining after welding because the supporting part and fixing members of a specimen holder are made of an insulating material. CONSTITUTION: A jig apparatus of a resistance spot welding machine comprises first and second arms(110,120), a specimen holder(130), and a support. The first and second arms are connected to the body of a resistance spot welding machine on one end thereof. The specimen holder comprises a supporting part(131), an electrode hole(132) which is formed through the supporting part to insert a lower electrode of the resistance welding machine, and one or more fixing members(133) which are arranged on the supporting part to fix a specimen for resistance spot welding. The support is formed at the other end of the second arm and supports the specimen holder. |
