2/0 Gauge AWG 150 Ft Black Flexible Pure Copper Welding Cable - Heavy

In this review of the 2/0 gauge TEMCo welding cable, the bottom line is simple: it is a heavy duty, extremely flexible pure copper cable suited to demanding DC power and welding tasks where durability and flexibility matter. The reviewer found it most valuable for battery, inverter and solar runs as well as welding leads because of its annealed OFC conductor and rugged EPDM jacket, which together deliver both conductivity and resistance to oil, abrasion and heat in tight routing situations.

Key Features

• 325 Max Amps: Delivers adequate current for many welding and heavy DC applications up to about 50 ft without excessive voltage drop.
• Rated to 600 volts: Provides insulation margin for a wide range of battery, inverter and low-voltage industrial uses.
• Wide temperature range: Operates from -58F to +221F, so it tolerates cold starts and hot engine bays without embrittling.
• Easy-Flex EPDM jacket: The rugged rubber jacket stays flexible for routing in vehicles, trailers and equipment while resisting cuts and abrasion.
• Annealed OFC conductor: High strand count (1196/30) ensures good flexibility and consistent copper content for conductivity and longevity.
• Multi-purpose use: Works for welding leads, battery and starter cables, car audio, solar arrays, RV/DC systems and winch power leads.

Who It's For

This cable is intended for DIYers, mechanics and small fabricators who need a heavy duty, flexible DC cable for welding leads, battery banks, or vehicle power runs. It is especially useful where routing through tight spaces or around bends is required and where an EPDM jacket resisting oil and heat is beneficial.

Those who should look elsewhere include people who require extremely long runs beyond the recommended amp-distance, or installers needing a tinned conductor for coastal corrosion protection; for those cases seek a different construction or larger gauge to match the longer distance or environment.

Pros & Cons

Pros

• High flexibility from a 1196/30 annealed OFC construction makes it easy to route and clamp.
• Rugged EPDM jacket resists cuts, oil, grease and abrasion for durable field use.
• Good current capability for shorter runs, with a 325 amp practical rating up to roughly 50 ft.
• Wide temperature tolerance covers both cold-weather work and hot engine compartments.

Cons

• Not intended for very long high-current runs without checking voltage drop; larger gauge may be needed.
• Conductor is bare copper; installers in corrosive coastal environments may prefer tinned cable.

Our Verdict

The TEMCo 2/0 150 ft welding cable is a practical, value-minded choice for anyone needing a heavy duty, flexible pure copper cable for welding leads, battery banks, car audio or solar DC runs. Its combination of annealed OFC conductor and a rugged EPDM jacket make it durable in workshop and vehicle environments, though installers should size up for long, high-current runs or choose tinned conductors for severe corrosion exposure.

Frequently Asked Questions

Can this cable be used for welding leads?
Yes, it is suitable for welding leads and similar DC power applications, with a practical maximum amp use of about 325 Amps for runs up to around 50 ft.

Is the jacket oil and abrasion resistant?
Yes, the TEMCo Easy-Flex EPDM jacket is resistant to cuts, tears, abrasion, water, oil, grease and flame, making it durable in engine bays and workshops.

Is the conductor tinned?
No, the conductor is annealed oxygen free copper (OFC) with high strand count; choose a tinned option separately if you need extra corrosion resistance.
