Resistance spot welding device

摘要

In order to carry away the relatively large amount of heat which is produced in the welding device particularly when welding tin-plated sheet metal because of the relatively large amount of welding energy, it is proposed according to the invention to provide sodium as coolant and heat-conducting means in the electrode cap or in the electrode adapter in the region of the electrode cap. As a result, the reduction of the service life of the electrode cap which otherwise arises due to the increased quantity of heat can be compensated.
