Power Joint

The Power Joint torch system perfects the interaction between welding machines and robots with an internal torch cable. The rotating joint of the Power Joint features unlimited rotation (beyond 360°, no stop) and supports the transmission of power, gas, air and wire. Compared to competitive solutions, the Power Joint can endlessly rotate about its own axis in either direction.

Another advantage: Disconnecting the torch cable from the torch movements eliminates any torsional strain on the cable thereby significantly increasing the lifetime of the torch cable. Consequently, the use of the Power Joint also increases the availability of the overall plant.

Thanks to its low weight and innovative design, the Power Joint helps the robot to make full use of its maneuverability. Time-consuming reversing of the hand axis or limitations of the articulation axis are a thing of the past – the robot can reach any desired point by the shortest possible path. This also leads to considerably less effort during the teaching of the robot.

The SKS collision protection for highest precision 

For the event of a collision with the workpiece or fixture, the Power Joint is equipped with integrated collision protection. The torch neck can deflect up to 10° to protect the torch and robot from damage. When the preset switch-off point is reached, an electric switching contact signals the collision to the robot controller. When resetting from a deflection, the internal spring system returns the torch neck to its original position (Tool Center Point, TCP) with an accuracy of ± 0.2 mm.
