PURPOSE: A welding machine for vehicle assembling is provided to improve working efficiency by removing a need of rotation of a jig. CONSTITUTION: A first tip(110) is installed on the upper face of a welding point of a base panel, and a second tip(112) is installed on the lower face. The tips are connected via bus bars(114,116) to extend out of a workpiece. Terminals(121,122) are connected to the ends of the tips. An insulator(124) is interposed between the terminals. Thus, a tack-welding gun(101) is produced. A high voltage feeding unit(130) generates high voltages to make the tip of the high voltage feeding unit contacted with the terminal of the tack-welding gun. According to the tack-welding gun, welding is performed at a remote place. Thereby, a jig is not to be rotated and working efficiency is improved.
