ABSTRACT:
A battery powered dent puller for re-contouring sheet metal having a dent is disclosed. A direct current welding electrode mounted on a handle allows the user to attach the electrode to an indentation in sheet metal with a very brief surge of 12 volt direct current. The welding current is regulated by means of a switch mounted on the handle which controls a relay through which the current travels. Once the electrode is attached on the sheet metal, the user may pull with considerable force in a direction that is generally in-line with the electrode. The force of the user pulling on the sheet metal tends to alter the contour of the metal, thus pulling out the indentation. To disengage the electrode from the sheet metal, the user twists the electrode, which breaks the weld. The battery power supply allows portability, increases safety, and tends to reduce assembly costs.
