2 Gauge AWG 500 Ft Black Flexible Pure Copper Welding Cable - Heavy

In this review of the 2 gauge AWG 500 ft black TEMCo welding cable, the bottom line is straightforward: this is a heavy duty, highly flexible pure copper cable aimed at installers and DIYers who need durable battery, welding, or solar DC cable for extended runs. The reviewer found the cable's greatest strength to be its combination of annealed OFC copper conductors and a rugged EPDM jacket that stays flexible in cold or hot engine bay conditions, which makes it a versatile choice for battery banks, winch leads, and inverter or solar wiring.

Key Features

• 205 Max Amps: Provides reliable current capacity for runs up to about 50 ft, suitable for many battery and welding starter setups.
• Rated to 600 volts: Offers insulation safety margin for DC systems in vehicles, RVs, and small solar installations.
• Wide temperature range: Performs from -58F to +221F, so the jacket stays flexible in cold climates and resists softening in heat.
• Annealed 30 gauge OFC conductor: Oxygen free copper stranding improves conductivity and bending life compared with solid or lower-quality copper cores.
• Rugged EPDM jacket: The casing resists cuts, abrasion, oil, grease and flame, which helps in engine bays and outdoor installations.
• Flexible construction: The 624/30 conductor stranding and nominal 0.413 in diameter make the cable easy to route through tight spaces and around mounts.

Who It's For

This cable is best for installers and hobbyists who need a heavy duty, flexible DC cable for automotive battery cables, winch leads, car audio, RV and camper electrical systems, and small solar or inverter runs. Its pure copper and EPDM jacket make it particularly useful where both conductivity and mechanical toughness matter.

Those doing long high-current commercial welding runs beyond the recommended amp-distance or needing UL-listed specifics for industrial fixed wiring should look elsewhere; this product is optimized for battery, starter and portable welding or DC power applications rather than fixed building wiring with specific certification needs.

Pros & Cons

Pros

• High flexibility from annealed OFC and fine 624/30 stranding makes routing and bending simple.
• Durable EPDM jacket resists cuts, abrasion, oil and flame for engine bay and outdoor use.
• Wide temperature tolerance keeps the jacket workable in extreme cold and heat.

Cons

• 205 amp rating applies to runs up to about 50 ft, so longer high-current runs will need larger gauge or parallel conductors.
