Abstract
A tool for recontouring metal such as dents in the body of an automobile, for use in conjunction with an electrical welding apparatus, including a shaft on which a weight reciprocates, the weight being permitted to selectively collide with structure provided by the shaft to impart a force to the shaft along the longitudinal axis thereof, a portion of the shaft being electrically conductive and electrically connected to the electrical welding apparatus, the electrically conductive portion of the shaft for contacting the metal surface to be straightened, activation of the electrical welding apparatus welding the electrically conductive portion of the shaft to the surface to be straightened so that the forces transferred to the shaft by the weight can act upon the surface to be straightened. One embodiment of the present invention is configured to cooperate with the electrode provided by commercial electrical welding apparatuses while a second embodiment shows a configuration for wiring the tool directly to a cable which in turn can be connected to various types of welding apparatuses.
