Shunting Pliers

Description

• Squeeze-type resistance spot welding (STRSW) sometimes requires additional measures, in the form of shunting the current flow, to create a successful spot weld.
• Conductive coatings on steel, such as zinc or weld-through primer increase the resistance but a successful weld can be accomplished.
• Non-conductive coatings on steal, such as E-Coat (a corrosion-resistant primer applied to parts by the manufacturer) inhibit the completion of the spot weld.
• The E-Coat on the mating surfaces can be saved when using STRSW with the use of the Dent Fix Shunting Pliers (DF-SP360).
• Simply 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 facilitates the electrical current from one side to the other. The E-coat at the mating surface burns away.
• The process is very quick and despite the fact most of the current flows between the electrode tips the current detour was brief but necessary.
• Max amperage: 145 amps
• Copper Wire: 4 Gauge
