Abstract
In a flash welder, instead of using a flexible conductor, the electrical connection to the moveable electrode table is made by a connecting conductor which is slidably connected both to the moveable electrode table and the secondary of the welding transformer. The connecting conductor is mounted on the moveable electrode table in such a manner that, during non-welding periods, it may be retracted within the moveable table, disconnecting it from the transformer and thereby clearing the space between the electrode tables for other workpiece machining operations.
