In general, in the production line of cold rolled products, several hot coils are connected in series to produce the product by continuous operation. Usually, the wires and rear ends of the preceding steel plate (coil) and the following steel sheet (coil) are connected by welding and then put into continuous operation. The welding operation of such a line and a subsequent steel sheet is schematically shown in FIG. 1, and a plated layer of zinc plating, tin plating, etc. is formed on the surface of the steel sheet to be introduced at this time.

That is, as shown in Figure 1, in the state in which the ends of the preceding and succeeding steel sheet 100, 110 is shown schematically in the drawing, the welding wheel 120 of the welder each steel sheet 100, 110 While proceeding in the width direction of the high-voltage current was applied to perform the welding operation of the line, trailing steel plate (100) (110).
