2 Gauge 150 ft Black + 150 ft Red Welding Cable - Flexible Pure Copper

In this review the TEMCo 2 gauge welding cable is evaluated for anyone needing heavy duty, flexible battery or welding leads. The bottom line: it is best for installers and hobbyists who want a rugged, highly flexible pure copper cable that handles up to 205 amps for short runs and resists oil, water and abrasion. Reviewers will find the cable stands out for its flexibility and construction, making it a practical choice for solar, car audio, RV or battery bank work where durability and heat resistance matter.

Key Features

• Pure copper conductor: Annealed oxygen free copper strands provide reliable conductivity and corrosion resistance for battery and welding use.
• High flex EPDM jacket: The rugged jacket delivers exceptional flexibility and abrasion resistance for tight routing and repeated handling.
• Temperature range: Rated from -58F to +221F so it remains usable in very cold or hot engine bays and outdoor installations.
• Voltage and amp rating: Rated up to 600 volts and 205 max amps (up to 50 ft) for a variety of DC applications including winches and inverters.
• Stranding and size: Fine 624/30 stranding with a nominal OD of 0.413 in gives a balance of flexibility and cross sectional copper area.
• Chemical resistance: The jacket resists water, oil, grease, cuts and tears so it holds up in harsh workshop or vehicle environments.

Who It's For

The cable is ideal for DIY installers, automotive enthusiasts, and small solar or RV systems that need flexible, heavy duty battery or welding leads. Its pure copper and EPDM construction suits applications where repeated movement, routing through tight spaces, or exposure to oils and heat are expected.

Those who need extremely long weld leads for professional shop welding at higher sustained amps or who require formal UL listings for commercial projects should compare alternatives; this cable is primarily targeted at durable, flexible DC wiring and battery connections rather than certified high-voltage AC installations.

Pros & Cons

Pros

• Very flexible construction makes routing and handling simple in tight spaces.
• High temperature rating and oil/abrasion resistance hold up in engine bays and outdoor use.
• Pure annealed oxygen free copper stranding gives solid conductivity for battery and inverter connections.

Cons

• 205 amp rating applies to shorter runs (up to 50 ft), so longer runs will need larger gauge or parallel runs.
