摘要：A resistance welding system includes a plurality of first electrodes, and a second electrode which is provided facing the plurality of first electrodes and which is electrically connected to a welding power source. The welding system welds a plurality of weld members sandwiched between the plurality of first electrodes and the second electrode by resistance welding. A current feed roller which is electrically connected to the welding power source and which rotates while successively contacting the plurality of first electrodes for successively feeding current to the plurality of first electrodes and a pressing device which is designed to move in the rolling direction together with the current feed roller and presses the current feed roller so as to successively apply welding pressure to the plurality of weld members W are included in the resistance welding system.

主权项：1. A resistance welding system comprising a plurality of first electrodes and a second electrode provided facing said plurality of first electrodes and electrically connected to a welding power source and which welds a plurality of weld members sandwiched between said plurality of first electrodes and said second electrode by resistance welding, said resistance welding system further comprising: a current feed roller that is electrically connected to the welding power source and adapted to successively contact the plurality of first electrodes when the current feed roller moves by rolling such that the current feed roller contacts each one of the plurality of first electrodes one at a time to feed current to the plurality of first electrodes, the current feed roller having a current feed roller support member, a pressing device that is designed to move together with the current feed roller in the rolling direction and which successively applies welding pressure to the plurality of weld members such that pressing device applies welding pressure to each of the plurality of weld members one at a time, the pressing device having a frame, wherein the current feed roller support member is supported by the frame, and an electrode holder which holds the plurality of first electrodes aligned together, the holder being comprised of an electrical insulating material to electrically insulate the plurality of first electrodes from each other.
