TEMCo 6 Gauge AWG 85 ft Black Flexible Pure Copper Welding Cable

Our review of the TEMCo 6 gauge AWG 85 ft welding cable finds it best for DIY mechanics, off-grid solar installers, and vehicle owners who need a long, flexible battery or welding lead that is genuinely copper and built to last. The single biggest reason to buy is its combination of highly flexible annealed OFC conductor and a rugged EPDM jacket that resists cuts, oil, water and abrasion, making it easy to route in tight spaces while staying reliable under heavy use.

Key Features

• 115 Max Amps: Provides a practical current capacity for runs up to 50 ft, suitable for many battery, starter and light welding tasks.
• Rated to 600 volts: Gives insulation confidence for DC systems like solar arrays, inverter feeds and battery banks.
• Wide temperature range: Operates from -58F to +221F, so it performs outdoors, in vehicles and in colder climates without becoming brittle.
• Annealed 30 gauge OFC conductor: The oxygen free copper stranding offers good conductivity and the 260/30 stranding ensures notable flexibility for tight bends.
• Rugged EPDM jacket: The durable rubber outer layer resists cuts, tears, oil, grease and flame which helps the cable survive rough use in workshops and vehicles.
• Versatile use: Works for welding leads, starter and battery cables, car audio, RV and solar DC systems, and winch power leads, making it a multi-purpose heavy duty wire.

Who It's For

This cable is aimed at hands-on users who need a robust, flexible conductor for medium-duty power tasks: hobby welders, vanlifers wiring battery banks, car and truck owners replacing starter cables, and solar DIYers wiring low-voltage DC runs. The 85 ft length is especially useful when routing around frames or between battery banks and inverters.

It is less appropriate for heavy industrial welding where larger gauge leads or higher continuous current capacity are required, or for mains AC wiring where code-rated building wire is necessary. Users who need permanently installed building wiring should look to products specifically listed for that application.

Pros & Cons

Pros

• Flexible annealed OFC conductor with dense 260/30 stranding makes routing and connector termination easier.
• Durable EPDM jacket resists abrasion, oil and moisture for longer field life.
• Suitable temperature range and 600 V rating give confidence for automotive, RV and solar DC use.

Cons

• The listed 115 max amps is realistic for moderate runs but users needing high continuous welding current should choose larger gauge cable.
• Nominal OD of 0.303 in may be bulky in very tight conduit or when space is extremely limited.

Our Verdict

The TEMCo 6 gauge 85 ft welding cable is a practical, value-minded choice for battery cables, light welding leads and solar or RV DC systems where flexibility, durability and true copper content matter. It is good value for owners who need a long, resilient cable that resists oil and abrasion, but those needing very high continuous welding current should opt for a heavier gauge.

Frequently Asked Questions

Can this cable be used for car starter cables?
Yes, it is suitable for battery and starter cable use in cars, trucks and diesel vehicles where 6 AWG meets the application needs.

Is the conductor real copper?
Yes, the cable uses annealed OFC (oxygen free copper) with 260/30 stranding, which customers note for its visible copper strands and conductivity.

Can it be buried or used outdoors?
The EPDM jacket resists water and oil and the temperature range supports outdoor use, but permanent buried installations should follow local code and additional protection when required.
