OVERVIEW

Premium 2/0 AWG Welding Cable – 50ft Coil

Upgrade your welding setup with the superior performance of our 2/0 AWG Welding Cable. Sold in a convenient 50-foot coil, this cable is the ideal solution for welders looking to extend their reach or replace damaged leads. At Welders Supply, we understand that the quality of your leads directly impacts your weld quality and comfort. That’s why this cable is designed with a focus on flexibility and durability, ensuring it stands up to the daily grind of professional welding while remaining easy to handle.

The core of this cable consists of fully annealed, stranded bare copper. Unlike stiffer cables, the high strand count (Class K) delivers exceptional flexibility, allowing the cable to lay flat and coil easily at the end of the day. This "limp" feel is highly prized by welders as it reduces the strain on your wrist and arm during long welding sessions. The 2/0 gauge size is perfect for medium to heavy-duty applications, capable of handling significant amperage loads (typically rated around 300-400 amps depending on duty cycle) without overheating.

Durability is ensured by a tough, high-dielectric insulation jacket. This black jacket is specifically formulated to resist the sparks, spatter, and sharp edges found in metalworking shops. It is also impervious to oil, water, and grease, preventing the insulation from swelling or rotting. Beyond welding, this high-quality 2/0 cable is frequently used for automotive battery relocation, solar power inverter wiring, and heavy-duty jumper cables due to its excellent power transfer capabilities and rugged construction. Get the reach and reliability you need with this professional-grade power cable.

FAQ

The amperage rating depends on the duty cycle and cable length. Generally, 2/0 welding cable is rated for approximately 300 Amps at 100% duty cycle, and can handle higher amperages (up to 400-450A) at lower duty cycles (e.g., 60% or 30%). Always consult the specific ampacity chart for your total circuit length.

This is premium welding cable made with stranded bare copper conductors. We do not sell CCA welding cable as it does not offer the same conductivity or durability as pure copper.

The outer diameter (OD) of standard 2/0 welding cable is typically between 0.56 and 0.60 inches, depending on the specific insulation thickness of the batch.

Yes, 2/0 welding cable is excellent for battery interconnects, solar setups, and car audio due to its high flexibility and fine copper strands, which carry current very efficiently.

Yes, the EPDM/Neoprene jacket is engineered to be resistant to oil, grease, gasoline, and other common industrial chemicals, preventing the insulation from breaking down.

No, this is a bulk 50-foot coil of raw cable. Lugs, electrode holders, and ground clamps must be purchased separately and installed.

This welding cable is rated for a temperature range of -50°C (-58°F) to +105°C (+221°F), making it suitable for both extreme cold and high-heat environments.

No. Welding cable is not rated for in-wall use or standard household AC wiring (NEC standards). It is designed for secondary voltage welding leads and DC power applications.
