2/0 Gauge Welding Cable 175 ft Red - Flexible Pure Copper Heavy Duty

Our review of the TEMCo 2/0 gauge 175 ft red welding cable finds it best suited to users who need a long, heavy duty, highly flexible battery or welding lead that holds up in harsh environments. The single biggest reason to buy is the combination of annealed oxygen free copper conductor and a rugged EPDM jacket, which delivers both conductivity and flexibility for applications from welding to solar and car audio wiring. It feels like a purposeful cable for DIYers and professionals who need durable, heat- and oil- resistant power cable over long runs.

Key Features

• 325 Max Amps: Handles up to 325 amps for shorter runs and maintains reliable current capacity for welding and battery feeds up to recommended distances.
• Rated up to 600 volts: Provides a safe insulation margin for DC systems such as solar arrays, inverters, and battery banks.
• Wide temperature range: Rated from -58F to +221F so it tolerates engine bay heat and outdoor conditions without becoming brittle or softening excessively.
• Annealed OFC conductor: The 1196/30 stranding of oxygen free copper offers excellent flexibility and conductivity for tight bends and frequent handling.
• Rugged EPDM jacket: The rubber jacket resists cuts, abrasion, water, oil, grease and flame which suits harsh workshop and vehicle use.
• Versatile applications: Works not only for welding but also as battery and starter cable, solar wiring, car audio, RV DC systems and winch leads.

Who It's For

This cable is ideal for hobby welders, mobile installers and vehicle owners who need a long run of heavy gauge, flexible copper for battery banks, starters, or solar systems. Installers who value a rubber jacket that stands up to grease, oil and heat will appreciate the build and flexibility.

It is less suitable for users who need ultra-high current for very long welding leads beyond recommended amp/length limits or who require a colored jacket beyond the supplied red for both conductors in a paired run. For extreme high-current industrial feeders, a custom-specified bulk cable may be a better choice.

Pros & Cons

Pros

• Excellent flexibility from fine annealed 30 gauge stranding makes routing and terminations easier.
• Durable EPDM jacket resists oil, grease, abrasion and flame for vehicle and outdoor use.
• Pure oxygen free copper conductor provides good conductivity and long-term durability in hot engine bays.

Cons

• Nominal outer diameter of 0.564 in makes it fairly bulky for tight conduit or multi-cable trays.
• Single color jacket means you must label or pair it to identify polarity in multi-cable installations.

Our Verdict

The TEMCo 2/0 gauge 175 ft red welding cable is a practical, value-minded choice for anyone needing a long, flexible pure copper lead that endures heat, oil and abrasion. It works well across welding, battery and solar projects, offering good conductivity and durability for the price; installers who need extreme compactness or dual-color runs should plan accordingly.

Frequently Asked Questions

Can this cable be used for solar and inverter connections?
Yes, it is rated up to 600 volts and is suitable for solar, inverter and battery bank DC connections when sized correctly for current and run length.

Is the conductor truly pure copper and flexible?
Yes, the cable uses annealed oxygen free copper with 1196/30 stranding, which gives it high flexibility for routing and terminations.

How resistant is the jacket to engine bay conditions?
The EPDM jacket is formulated to resist cuts, abrasion, water, oil, grease and heat across the specified temperature range, making it appropriate for engine bay use.
