OVERVIEW

Industrial Grade 4/0 AWG Welding Cable

This premium 4/0 (0000 AWG) welding cable is designed for the most demanding industrial applications where high amperage and durability are critical. Engineered with a high strand count of annealed bare copper, this cable falls under Class K stranding, providing exceptional flexibility despite its large diameter. This flexibility is essential for reducing operator fatigue during long welding shifts and allows for easier installation in complex cable trays or tight machinery housings.

The insulation consists of a high-grade Ethylene Propylene Diene Monomer (EPDM) rubber jacket. EPDM is the industry standard for professional welding cables due to its outstanding dielectric strength and physical toughness. It offers superior resistance to abrasion, cuts, tears, and impacts that are common in heavy manufacturing environments, shipyards, and construction sites. Furthermore, the jacket is chemically resistant to oils, grease, solvents, water, and ozone, ensuring the cable maintains its integrity even when exposed to harsh elements or shop fluids.

Rated for 600 Volts and a temperature range of -50°C to +105°C, this cable is suitable for a wide variety of power applications beyond just welding. It is frequently utilized for secondary voltage resistance welding leads, power supply applications, heavy-duty battery banks, and temporary power distribution. When calculating amperage capacity, this 4/0 cable can handle significant current loads, often rated up to 600 amps for intermittent duty cycles, making it the go-to choice for heavy industrial arc welders and power grids.

Ordering Information: This product is sold by the foot to minimize waste and cost. Simply input the total number of feet required in the quantity field, and a continuous length will be provided. Whether you are outfitting a fleet of welding machines or wiring a large-scale solar battery bank, this 4/0 cable delivers the performance and reliability required for professional electrical connections.

FAQ

4/0 welding cable is generally rated for up to 600 amps for short runs (under 50ft) at a 30-50% duty cycle. For continuous use or longer runs, the rating is typically around 300-400 amps. Always consult an ampacity chart based on your specific length and temperature requirements.

This is standard professional welding cable featuring fully annealed stranded bare copper conductors. It is NOT Copper Clad Aluminum (CCA), ensuring maximum conductivity and flexibility.

The outer diameter (OD) of 4/0 welding cable is typically between 0.72 and 0.82 inches, depending on the specific manufacturer's insulation thickness.

Yes, 4/0 welding cable is an excellent choice for battery interconnects and inverter wiring due to its high flexibility and ability to handle high current loads with minimal voltage drop.

Yes, the EPDM rubber jacket is engineered to resist abrasion, oil, grease, solvents, water, and ozone, making it highly durable in automotive and industrial environments.

This product is sold by the foot. Enter the total number of feet you wish to purchase in the quantity box, and we will cut a single continuous length for you.

This welding cable is rated for 600 Volts, which is standard for secondary welding leads and many DC power applications.

Absolutely. Despite its large size, the high strand count (Class K) makes it very flexible, reducing wrist fatigue when used as a stinger or electrode holder lead.
