1/0 Gauge AWG 175 ft Black Pure Copper Welding Cable - Flexible, Heavy

In this review the TEMCo 1/0 gauge 175 ft welding cable is evaluated for DIYers and professionals who need a long, flexible heavy duty cable for battery, solar or welding use. The bottom line: this cable stands out because of its combination of pure annealed OFC copper and a rugged EPDM jacket that stays pliable in cold weather, making it ideal where flexibility and reliable conductivity matter. The review focuses on real-world durability, temperature tolerance and common applications where the cable delivers noticeable value.

Key Features

• Pure copper conductor: Annealed 30 gauge oxygen free copper strands provide excellent conductivity for battery, starter and welding leads.
• High amp capacity: Rated up to 285 max amps (up to 50 ft), which is useful for many welding and high-current DC tasks.
• Wide temperature range: Usable from -58F to +221F, so it remains flexible in cold climates and holds up near engine bay heat.
• Rugged jacket: The EPDM outer jacket resists cuts, tears, abrasion, water, oil, grease and flame for demanding environments.
• Heavy duty size: Nominal OD 0.526 in with 975/30 conductor stranding gives a good balance of flexibility and current carrying capacity.

Who It's For

This cable is a solid choice for installers and hobbyists wiring battery banks, solar arrays, winch leads, car audio systems or using long welding leads where flexibility and pure copper conductivity are priorities. Its long 175 ft length also suits runs where avoiding splices is important.

Those who need UL listed appliance cord for household wiring or who require insulated high-voltage AC cable should look elsewhere, since this product is intended for DC and welding uses at up to 600 volts and not as building wire for mains circuits.

Pros & Cons

Pros

• Very flexible EPDM jacket stays pliable in cold weather and is easy to route in tight spaces.
• Pure annealed OFC copper gives dependable conductivity and longevity for battery and welding applications.
• Durable construction resists oil, grease, abrasion and flame for engine bays and workshop use.

Cons

• 275-285 amp rating applies to shorter runs; voltage drop over very long runs may require larger gauge or multiple runs.

Frequently Asked Questions

Can this cable be used for battery banks?
Yes. The pure copper conductor and heavy duty jacket make it well suited for battery banks and starter cables in vehicles and solar systems.

Is the cable flexible in cold weather?
Yes. The EPDM jacket and fine 975/30 stranding keep the cable flexible down to -58F, which helps routing in cold conditions.

Will this handle long welding leads without voltage drop?
It is rated 285 amps up to about 50 ft; for very long welding runs voltage drop can become significant and a larger gauge or parallel runs may be needed.
