TEMCo 4-Gauge Welding Cable 25ft Black + 25ft Red – Pure Copper, Made in USA

Powerful, flexible dual-color cable set for heavy-duty wiring

TEMCo Easy-Flex 4 AWG welding cable arrives as a matched pair: 25 ft in black and 25 ft in red, ready to help you route power with clear polarity cues. Built for durability and ease of handling, the pair features an annealed pure copper conductor and a rugged EPDM jacket. This combination provides both conductivity and flexibility, so you can bend and guide the leads through tight engine bays, panels, or cargo areas without kinking. The set is proudly made in the USA, underscoring TEMCo's commitment to rugged, reliable wiring solutions.

The conductor uses a fine strand construction (364/30) that feels supple in your hand, which translates to smoother bends and less fatigue when routing long runs or weaving around components. The copper’s natural shine remains visible through the protective jacket, hinting at high conductivity and low resistance for demanding lead applications. The jacket is designed to resist cuts, tears, abrasion, water, oil, grease, and flame, giving you a confident option for shop, garage, and field use.
