2/0 Gauge AWG 175 ft Black Flexible Pure Copper Welding Cable - Heavy

Our review of the 2/0 gauge TEMCo welding cable finds it best suited for DIYers and small shops needing a flexible, heavy duty battery or welding lead with dependable copper conductor. The single biggest reason to buy is its combination of high flexibility and true oxygen free copper construction, which makes routing in tight engine bays, RV compartments and solar battery banks far easier than stiff alternatives. Temperatures from -58F to 221F and a rugged EPDM jacket mean it performs in harsh environments without feeling overpriced.

Key Features

• 325 Max Amps: Provides ample current capacity for welding and battery use at typical run lengths up to 50 ft for durable performance.
• Rated to 600 volts: Suitable for a range of DC systems including solar, inverter and starter battery applications.
• Wide temperature range: Operates from -58F to 221F so it holds up in cold storage, engine bays and hot outdoor installations.
• Oxygen free copper conductor: Annealed 30 gauge OFC stranding yields excellent conductivity and long life under flexing conditions.
• Rugged EPDM jacket: The rubber jacket resists cuts, abrasion, oil and grease, improving durability where exposure is likely.
• Highly flexible construction: The fine 1196/30 stranding makes routing and termination simpler than thicker, stiffer cables.

Who It's For

This cable suits hobby welders, automotive and marine DIYers, and small-scale solar installers who need a flexible, heavy duty conductor for battery, starter or winch leads. The flexibility and pure copper construction are useful where space is constrained or repeated movement is expected.

Those who need ultra long runs above 50 ft for sustained welding at high amps or who require insulated multi-conductor cable for AC house wiring should look elsewhere; this product is targeted at DC/battery/welding and single-conductor power runs rather than mains building wire or multi-core assemblies.

Pros & Cons

Pros

• Excellent flexibility that simplifies routing in tight spaces and around engine components.
• Durable EPDM jacket offers resistance to cuts, abrasion, oil and flame for rugged field use.
• Pure annealed OFC conductor gives reliable conductivity and longevity for battery and welding tasks.

Cons

• At long lengths beyond 50 ft the effective amperage capacity drops, so for high-amp welding runs a larger gauge or shorter run is preferable.

Frequently Asked Questions

Can this cable be used for solar battery banks?
Yes. The 600 volt rating, flexible OFC conductor and rugged jacket make it suitable for DC solar battery and inverter connections.

Is it safe to run in an engine bay?
Yes; customers note it holds up well to engine bay heat and the EPDM jacket resists oil and grease, though routing clear of extreme heat sources is still recommended.

Will it work for long welding leads?
It will work, but amperage capacity is specified up to 50 ft at 325 amps; for longer high-amp welding runs choose heavier gauge or shorter cable to avoid voltage drop.
