The present invention relates to a welding current source for a welding apparatus, having inputs for control and load circuits, which are connectable to different electric power networks and are reversibly switchable. The gist of the invention is that a switchover device with first and second switchover mechanisms which are simultaneously actuatable by a common handle is provided, the first switchover mechanism connecting the control circuit to the inputs in a reversibly switchable manner, and the second switchover mechanism connecting the load circuits to the inputs in a reversibly switchable manner.
