PURPOSE:To facilitate carrying of objects to be welded by connecting a secondary side terminal of a welding transformer to the first plate and another one to the second plate and forming a circuit that connects the first and second plates when the place to be welded is held by the two electrode chips connected electrically. CONSTITUTION:A receiving face 36 that supports an object 5 to be welded, for instance the door of an automobile, having welding position 27 superposed each other, the first plate 38 fitted to the receiving face 36 in insulated state and the second plate 45 which is near the part other than welding part of the object 5 to be welded and can be connected to the above are installed. One of secondary side terminals 41 of a fixed welding transformer 31 is connected to the first plate 38, and another secondary side terminal 47 is conncted to the second plate 45. Two electrode chips 59, 60 of a welding gun 62 that presses the position 27 to be welded are connected electrically. The position 27 to be welded is pressed by these electrode chips 59, 60 to form a circuit that connects the first plate 38 and the second plate 45. |
