Abstract
A handling robot for a current-consuming appliance (e.g. a welding head) comprises a pivotal stand with a first arm which is rotatably journalled in the stand and a second arm which is rotatably journalled in the first arm. The second arm has a sleeve which is journalled in the first arm. In said sleeve, a portion with a holder for the appliance is rotatably journalled. From a transformer, the supply current for the appliance is conducted to a rotatable contact device and to two preferably concentric tubular electrical conductors through the rotatable portion. The tubular conductors are utilized as conduits for cooling water.
