By the pressing force of the screw clamps 8, the clamping bars are pressed onto the sheet metal edges and these onto the copper bar $ and thereby connected electrically Infinitely variable tractor tO for the electrode 15 glued into the extension piece 11 of its swiveling holder 12 • guided »Since the holder allows long or shortest electrodes to be placed in an inclined position on the butt joint 5 of the sheet metal and the copper rail 3 or their ignition studs 14 as well as the holder are connected to a welding current source, when the core tip touches the electrode with the ignition stud or the sheet metal tips at the start of the butt joint and after switching on the welding current and the 2ugmasehinen drive, the electrode will automatically burn off and weld the butt joint continuously. A correct welding of 4 sheets and the most economical consumption of electrodes is guaranteed if the thickness of the electrodes is adapted to the required welding current and the driving speed of the tractor is adapted to the desired weld strength. 1.
