Portable Copper Secondary Water Cooled Cable Stable Spot Welding Application

This Secondary Cable (Kickless Cable) is a precision connection component engineered to enhance the end-effector performance of dynamic welding systems. Its core value lies in its exceptionally small dynamic bending radius and minimal inductive interference, allowing for seamless integration at the tail of the welding gun. This significantly improves the operational agility and responsiveness of the gun in three-dimensional space. The compact, short-length design optimizes the power transmission path while substantially reducing installation complexity and long-term maintenance costs. It is a key enabler for achieving high flexibility, efficiency, and reliability in robotic welding cells and suspended welding systems.

• One-Piece Forged High-Conductivity Terminal: Terminals are made from ultra-high-purity electrolytic copper and formed via a one-time precision cold-forging process, achieving a zero-defect, dense microstructure. This ensures excellent high-frequency conductivity under the skin effect and maximizes current transmission efficiency and long-term stability at the physical connection level.

• Multi-Layer Composite Low-Loss Conductor: The conductor is manufactured from high-purity oxygen-free copper rods through multiple processes of drawing, tinning, and composite concentric stranding. This multi-layer composite stranded structure effectively suppresses high-frequency eddy current losses and the skin effect, delivering ultra-low impedance and superior fatigue resistance under high-current, high-duty-cycle operating conditions.

• Molecular-Level Connection Resistant to Dynamic Shock: Employs high-temperature-resistant diffusion welding technology or high-energy precision crimping processes to create a molecular-level metallurgical bond between conductor and terminal that withstands mechanical vibration and thermal cycling. This connection can endure the repeated electromagnetic force impacts of welding currents, completely preventing breakage and detachment, thereby doubling service life.

• Special Elastomer Composite Protective Jacket: The outer jacket utilizes a custom synthetic elastomer compound, formulated to achieve an optimal balance of dynamic flexibility, crush resistance, high-temperature/ozone aging resistance, and coolant corrosion resistance. Multi-color coding facilitates quick identification and maintenance within complex piping.

• Fully Sealed Hydraulic Locking Clamp: Connections are secured with high-strength stainless steel hydraulic clamps, high-pressure formed and sealed in one action by professional equipment. Compared to traditional clamps, they offer permanent anti-creep locking force, IP67 or higher protection rating, and a streamlined industrial appearance, ensuring a leak-free cooling circuit for the lifetime of the assembly
