2/0 Gauge 1000 Ft Black Flexible Pure Copper Welding Cable - Heavy

In this review of the TEMCo 2/0 gauge 1000 ft welding cable, the bottom line is simple: this is a heavy duty, highly flexible battery and welding cable for installers and DIYers who need dependable copper conductors across long runs. The main reason to buy is the combination of an annealed oxygen free copper core and a rugged EPDM jacket, which together deliver both conductivity and flexibility for solar arrays, battery banks, vehicle battery feeds and welding leads. The review focuses on build quality, real-world handling, and the situations where this cable shines.

Key Features

• 325 Max Amps: Provides a practical continuous amp capacity for runs up to 50 ft, making it suitable for many battery and welding setups.
• Rated to 600 volts: Offers insulation and safety margin for DC systems like solar arrays and inverter feeds.
• Wide temperature range: Rated from -58F to +221F so it stands up to cold storage and hot engine bay environments.
• Easy-Flex EPDM jacket: The rugged rubber jacket resists cuts, abrasion, oil and grease while remaining flexible for routing in tight spaces.
• Annealed OFC conductor: The 1196/30 stranded oxygen free copper gives low resistance and excellent flexibility for repeated movement.
• Nominal OD 0.564 in: A compact diameter for 2/0 cable that eases conduit and clamp choices while retaining capacity.

Who It's For

This cable is best for DIY electricians, solar installers, automotive and RV owners, or hobby welders who need long lengths of quality copper cable that will flex without breaking. The pure copper construction and heavy stranding suit battery banks, winch leads, starter cable upgrades, car audio and DC power runs where flexibility and conductivity matter.

Those who need lighter gauge wire, specialized high-voltage insulation beyond 600 volts, or pre-terminated assemblies should look elsewhere; this product is raw cable for custom installations and assumes the user will terminate or clamp it to appropriate lugs or connectors.

Pros & Cons

Pros

• High flexibility and durable EPDM jacket make routing and repeated movement easy.
• Pure annealed OFC conductor offers reliable conductivity and long life in high-heat areas.
• Good value for bulk 1000 ft spools used in solar, battery banks, and vehicle projects.

Cons

• The cable is raw and requires proper termination and strain relief; no pre-attached lugs are provided.
• At 2/0 gauge weight and diameter, handling long runs can be cumbersome for one person.

Specifications

Our Verdict

The TEMCo 2/0 welding cable is a practical, cost-effective choice for anyone building battery banks, solar DC runs, vehicle power upgrades or welding leads where flexibility and pure copper conductors matter. It delivers solid durability and thermal tolerance in a bulk spool, making it good value for installers who will terminate it themselves.

Frequently Asked Questions

Can this cable be used for solar DC array wiring?
Yes - it is rated to 600 volts and the EPDM jacket resists UV and oils, making it suitable for many solar and battery DC installations when properly sized and terminated.

Is the conductor truly pure copper?
Yes - the cable uses annealed oxygen free copper with 1196 strands for improved conductivity and flexibility.

Will it handle engine bay heat?
The temperature rating to +221F means it tolerates elevated temperatures typically found in engine bays, but proper routing and heat shielding are still recommended.
