TEMCo 6 Gauge AWG 20 Ft Black Flexible Pure Copper Welding Cable

In this review of the TEMCo 6 Gauge AWG 20 ft welding cable, the bottom line is simple: it is a practical, heavy duty cable for anyone who needs flexible, reliable DC power runs up to moderate lengths. The reviewer found the cable best for battery and starter leads, solar arrays, winch power runs and light welding hookup where up to 115 max amps is sufficient. Its standout trait is the highly flexible, rugged EPDM jacket combined with annealed oxygen free copper strands that make routing and long-term handling noticeably easier than stiff alternative cables.

Key Features

• 115 Max Amps: Provides adequate current capacity for battery cables, small welders and solar DC runs when used within recommended lengths.
• Rated to 600 volts: Gives flexibility to use the cable in a variety of low-voltage DC and some industrial applications.
• Wide temperature range: Durable performance from -58F to +221F makes it suitable for outdoor and vehicle environments.
• Easy-Flex EPDM jacket: A rugged rubber outer jacket resists cuts, tears, abrasion, water, oil, grease and flame for dependable field use.
• Annealed OFC conductor: Oxygen free copper with 260/30 stranding yields excellent conductivity and notable flexibility for routing in tight spaces.
• Nominal OD 0.303 in: Compact outside diameter that balances current capacity with easier handling and connector fitment.

Who It's For

This cable is aimed at DIYers, installers and vehicle owners who need a flexible, durable battery or power lead for car, truck, RV, camper or small solar installations. It is also a good fit for light welding tasks, winch power leads and battery bank interconnects where a flexible jacket and good copper content matter.

Professional welders running continuous high current for long periods or users who require thicker gauges for heavy-duty commercial welders should look for a higher ampacity cable; similarly, projects needing IEC-rated mains or insulation beyond EPDM requirements may need a different product.

Pros & Cons

Pros

• High flexibility from the annealed OFC conductor and EPDM jacket makes routing simple in tight spaces.
• Durable jacket resists common workshop and vehicle hazards like oil, abrasion and tears.
• Versatile use cases: battery cable, car audio, solar and light welding applications all work well.

Cons

• 115 max amps limits this cable for heavier welding or long high-current runs without upsizing.
