Zusammenfassung:	To provide a relay body for welding, which is excellent in assemblability and maintainability.SOLUTION: A relay body 23 for welding, which is used to pass a welding current, is arranged between a welding power-supply unit and a welding torch, and composed of a metal conductor. The relay body for welding comprises a hollow gas passageway 231 which has a first opening 231a provided at one end and a second opening 231b provided at the other end and which is used to allow a flow of a gas, and a hollow cooling liquid passage 232 which has a third opening 232a provided at one end and a fourth opening 232b provided at the other end and which is used to allow a flow of cooling liquid.SELECTED DRAWING: Figure 2 【課題】組立て性やメンテナンス性に優れた溶接用中継体を提供する。【解決手段】溶接電源装置と溶接トーチとの間に配置され、且つ金属導体により構成されており、溶接電流を流すための溶接用中継体２３であって、一端に設けられた第１開口２３１ａおよび他端に設けられた第２開口２３１ｂを有し、ガスを流すための中空状のガス通路２３１と、一端に設けられた第３開口２３２ａおよび他端に設けられた第４開口２３２ｂを有し、冷却液を流すための中空状の冷却液通路２３２と、を備える。【選択図】図２
