A brazer head is described that is highly suitable for the automation of the weld repair process of conductive lines on printed circuit cards. For repairing a conductive line 1 which in position 2 has an insufficient cross-section a copper wire 3 is pulled off a coil 4 contained in a closed housing (not shown) that is under low air pressure. Supported by a DC motor (not shown), the pressure (air stream) feeds the wire softly to position 2 where it is fastened by lowering two molybdenum tips 5 and 6 of the brazer head, tip 6 being adjustable in the direction of the arrow by a DC motor. Then current is applied to tips 5 and 6 which weld copper wire 3 to conductive line 1.
