ABSTRACT:
A welding apparatus for plastic work pieces has two welding tables arranged next to one another. A propulsion device displaces the welding tables. The propulsion device has a drive motor and a propulsion rod assembly. The propulsion rod assembly has spatially separated double arm levers with two lever arms in each case. The two lever arms are each mounted in a rotatable manner on an axis of rotation and are in a mechanical state of rotary connection with one another. One set of lever arms is kinematically connected to one welding table and the other lever arms are kinematically connected to the other welding table. During rotary movement of the double arm levers, the welding tables are moved toward one another in one direction of rotation, and away from one another in the other direction of rotation.
