Rotating grounding in girth automatic welding applications, the drive part is rotated to bring the convenience of welding. Copper ground clip rotating all-copper die-casting, the use of advanced, high-quality materials, good conductivity and durability; high spiral nip firm, holding tight and difficult to EDM, disassembly is very convenient. Rotary effective solution when the container, pipe or boiler welding ground connection, good to avoid entangling the ground wire; for MIG, TIG, submerged arc welding, resistance welding, stud welding and various other ways of high-current ground welding. Widely used in shipyards, steel, oil platforms, motor car manufacture, curtain industry, auto parts and other industries.
