The Dent Fix Shunting Pliers, DF-SP360, allow non-conductive coated metals, like an E-Coat, to accept squeeze-type resistance spot welding (STRSW). The heavy duty copper pads and thick wire attachments shunt or redirect the current to bypass the non-conductive coating and eliminate the need to remove the entire coating. To use, remove the coating from only the outside surfaces, position the shunting clamp at the spot weld site and the spot weld is made at the adjacent site. The current chooses the path of least resistance when confronting the non-conductive E-Coat, the shunting pliers facilitate the electrical current from one side to the other and the E-coat at the mating surface burns away.
