This has the following disadvantages. (A) Since it is necessary to peel off the painted surface to supply the current of the primary side earth, there is a waste that the area of the painting work increases. (B) Each time a single component at the part to be damaged is changed, the painted surface must be peeled off to supply the secondary earth current, and the clamp connection of the secondary earth cable must be redone. Was troublesome. (C) Depending on where the damage is to be corrected, the distance from the secondary side ground current connection is long, the electrical resistance is high, the current is reduced, and the welding force is weakened. There was an inconvenience that it could not be corrected withdrawal because it came off. (D) As shown in FIG. 3, after the damaged portion is pulled out, the drawn-out surface bulges outward and becomes higher than the original surface as compared with the original surface. Due to the pressure applied to the iron plate at the time of correction, deformation due to distortion caused by material elongation occurred, and when correcting this distorted bulge, remove the main shaft pulled out from the joint of the secondary side plus cable holder, Replace it with a current short-circuit heating shrinkage drawing correction jig,
When the correction is performed using the jig provided on the drawer main shaft, the correction must be performed by changing the sliding hammer, which is troublesome and inconvenient. (E) When the damaged surface of the iron plate is hit at a place where the correction surface is higher than the original surface, it has to be replaced with a sheet metal hammer to make a smooth adjustment, and the correction is troublesome and inconvenient. The present invention has been made to solve these disadvantages.
