1 Gauge AWG 85 ft Black Flexible Pure Copper Welding Cable - Heavy

In this review of the TEMCo 1 gauge 85 ft welding cable, the bottom line is simple: this is a heavy duty, highly flexible cable for anyone who needs reliable DC power runs where durability and pure copper conductivity matter. The reviewer found it particularly well suited for long battery leads, solar array runs and vehicle battery setups because of its high strand count and rugged EPDM jacket. For users who want a cable that balances flexibility, abrasion resistance and heat tolerance, this cable is worth considering.

Key Features

• 240 Max Amps: Provides sufficient current capacity for many battery, inverter and welding runs up to about 50 ft without excessive voltage drop.
• Rated to 600 V: Suitable for a wide range of DC system voltages commonly used in solar, RV and automotive applications.
• Wide temperature range: Operates from -58F to +221F so it will withstand cold starts and hot engine bay or outdoor conditions.
• Annealed OFC conductor: Oxygen free copper with 767/30 stranding delivers excellent conductivity and flexibility for tight bends and routed runs.
• Durable EPDM jacket: The rugged jacket resists cuts, abrasion, oil and grease, which helps the cable survive in workshops and vehicle compartments.
• Versatile applications: Works for welding, battery and starter cables, car audio, solar and winch power leads, making it a multiuse cable for DIY and professional use.

Who It's For

This cable is best for DIYers, mobile electricians and hobbyists who need a flexible, high strand count battery or welding cable for cars, trucks, RVs and solar systems. The pure copper conductor and robust jacket make it a good fit where repeated handling, bending and exposure to grease or heat are expected.

It may be less appropriate for installations that require formal UL listing or where a thinner jacket or lighter gauge would be preferred for tight conduit runs. Also, if you only need very short runs under a few feet, a lower gauge or specialized starter cable might be more economical.

Pros & Cons

Pros

• Exceptional flexibility from 767/30 annealed OFC stranding makes routing around tight spaces easy.
• Rugged EPDM jacket resists abrasion, oil and grease so the cable holds up in engine bays and workshop floors.
• Wide operating temperature range and 600 V rating add confidence for outdoor and vehicle use.

Cons

• The cable is heavy and bulky at 1 gauge and 85 ft, so it may be cumbersome for casual users to handle or coil.
• Not a substitute for cables required to meet specific agency approvals in some regulated installations.

Specifications

Our Verdict

The TEMCo 1 gauge 85 ft cable is a durable, flexible choice for battery banks, inverter and welding leads where pure copper conductivity and a tough jacket are priorities. It represents good value for mobile and off-grid projects that demand abrasion resistance and heat tolerance, though it is bulky for casual use and not intended as a substitute for specially certified building wiring.

Frequently Asked Questions

Can this cable be used for solar battery banks?
Yes, the 600 V rating and 240 amp capability for shorter runs make it suitable for many solar and battery bank connections.

Is the conductor pure copper?
Yes, the cable uses annealed oxygen free copper (OFC) with fine 767/30 stranding for flexibility and conductivity.

Will it handle engine bay heat and oil exposure?
Yes, the EPDM jacket resists oil, grease and heat within the stated temperature range, making it appropriate for engine bay use in most cases.
