WC4X50 - #4 Gauge Flexible Welding Cable - 50 Foot Coil

Premium #4 AWG Industrial Welding Cable – 50 Foot Pack

The WC4X50 is a high-performance #4 American Wire Gauge (AWG) welding cable supplied in a convenient 50-foot coil. Engineered for the rigorous demands of industrial environments, this cable features a fully annealed stranded bare copper conductor. The fine stranding (typically Class K) ensures maximum conductivity and superior flexibility, allowing the cable to be routed easily around tight corners and obstacles without kinking or stressing the connections. This makes it an excellent choice for secondary voltage resistance welding leads where maneuverability is critical to operator efficiency.

Encasing the copper conductor is a heavy-duty EPDM (Ethylene Propylene Diene Monomer) jacket. This premium insulation is formulated to withstand the harshest shop conditions. It offers outstanding resistance to abrasion, cuts, and tears, ensuring a long service life even when dragged over concrete floors or around sharp metal edges. Furthermore, the jacket is chemically resistant to oil, grease, solvents, water, and ozone, preventing degradation that can lead to safety hazards or equipment failure. The cable is rated for operation in extreme temperature ranges, maintaining flexibility in cold environments down to -50°C and structural integrity in heat up to +105°C.

Beyond standard welding applications, this #4 AWG cable is highly versatile. It is rated for up to 600 volts, making it suitable for various power supply applications, battery bank wiring, and heavy-duty jumper cables. Its compliance with industry standards, such as SAE J1127, guarantees reliable performance and safety. Whether used for replacing worn-out leads on portable welding machines or for custom power installations, the WC4X50 provides the electrical efficiency and physical durability required by professional technicians and engineers.
