Cooling system for weld device and robot system

Abstract

To provide a cooling system for a weld device which can adequately cool the weld device, even when the weld device is re-operated.SOLUTION: A cooling system 100 for a weld device 12 includes a pump 20 which pumps a cooling medium into the weld device 12 used in a welding process using a robot 10, a radiator 30 which cools the cooling medium flowing out of the weld device 12, a circulation flow passage 60 in which the cooling medium circulates through the pump 20, the weld device 12, and the radiator 30, and a bypass passage 80 for making the cooling medium flowing out of the pump 20 bypass the weld device 12 to flow into the radiator 30.SELECTED DRAWING: Figure 1
