6 Gauge AWG 20 Ft Red Flexible Pure Copper Welding Cable - Durable

In this review of the TEMCo 6 gauge 20 ft red welding cable the bottom line is simple: this cable is for anyone who needs a flexible, heavy duty copper lead for welding, battery or DC power work. The reviewer found the single biggest reason to buy is the combination of actual oxygen-free copper conductor and a rugged EPDM jacket that stays pliable in cold weather, so it performs well across tasks from starter/battery leads to solar and inverter runs.

Key Features

• 115 Max Amps: Capable of carrying up to 115 amps for runs up to 50 ft, which suits medium-length battery and welding leads.
• 600 Volt Rating: Rated to 600 volts so it can be used safely in many DC systems including solar and inverter installations.
• Wide Temperature Range: Rated from -58F to +221F, the EPDM jacket remains flexible in cold and resists heat during heavy duty use.
• Annealed OFC Conductor: The 260/30 strand, annealed oxygen-free copper provides good conductivity and flexibility for repeated bending and routing.
• Rugged Jacket: The cable resists cuts, tears, abrasion, water, oil, grease and flame, making it well suited to workshop and outdoor environments.
• Versatile Uses: Works for welding, battery and starter cables, car audio, RV/van DC systems, winch leads and battery banks.

Who It's For

This cable is a practical choice for home mechanics, mobile electricians and DIY solar installers who need a flexible, heavy duty lead without stepping up to much larger gauge sizes. The flexibility and durable EPDM jacket make it a good match where repeated movement or outdoor exposure is expected.

It is less suitable for applications that require higher continuous current than 115 amps over long runs, or where a thicker gauge is mandated by code for very high current charging or welding rigs. Anyone needing multi-conductor wiring or insulated control cable should look elsewhere.

Pros & Cons

Pros

• Actual annealed OFC conductor with many strands provides excellent flexibility and apparent copper content.
• Rugged EPDM jacket resists oil, grease, abrasion and flame for workshop or outdoor use.
• Wide temperature rating keeps the cable flexible in cold and stable in heat.
• Versatile for welding, starter/battery, solar and RV DC uses, offering good value for money.

Cons

• Limited to about 115 amps for typical runs up to 50 ft, so not ideal for very high current welding setups.
• Single conductor cable only; projects needing bundled or shielded multi-conductor runs require different cable types.

Specifications

Our Verdict

The TEMCo 6 gauge 20 ft cable is a solid, good-value choice for users who need a flexible, durable copper lead for welding, battery or DC power tasks. Its oxygen-free copper strands and EPDM jacket deliver real flexibility and toughness, making it a dependable general-purpose cable for workshops, vehicles and solar setups.

Frequently Asked Questions

Can this cable be used for battery banks?
Yes, the cable is suitable for battery and starter cables, battery banks and similar DC applications within its current and length limits.

Is the conductor solid copper or copper clad?
The product uses annealed oxygen-free copper (OFC) strands, not copper-clad aluminum, providing better conductivity and flexibility.

Will the jacket remain flexible in cold weather?
Yes, the EPDM jacket is rated down to -58F and stays flexible for outdoor and cold-weather use.
