Welding Cable

What is Welding Cable

Welding cable is the electrical conductor for the welding current. It consists of a series of fine copper strands wrapped inside a non-conductive, durable jacket (typically some type of synthetic or natural rubber of various colors). The fine copper strands give welding cable more flexibility than other types of electrical conductors and the insulating jacket is designed to hold up to repeated movement over rough surfaces. As the current level increases (measured in amperage or amps), the diameter of the welding cable and resulting cross sectional area of the copper stranding needs to increase. 


Welding Cable Features

• EPDM insulation provides outstanding cut, abrasion and slag resistance
• Resistant to oil, chemicals, water, ozone, & solvents
• Red, Orange, Blue,Black jacket
• Other colors available upon request  

Welding Cable Applications

Welding Cable often used in demanding applications, welding cable is a secondary voltage-resistance cable for welding tools or as a power cable that is attached to generators and industrial machinery. For example, electric arc-welding tools typically rely on two separate cables for operation; one that acts as the primary power source for the device while the other supplies a secondary power source. While welding cable may not power the generator, it is required for the electrode.
Welding cables are durable and flexible and are a popular choice for entertainment or stage lighting cables, lighting and sound systems, and communication vans. They can also function as battery cables for cars, inverter cables, and as a more cost-effective alternative to pendant (or reeling) cable on hoists and cranes.

Welding cable “ampacity”, also known as current capacity or amperage rating, refers to the maximum amount of electrical current that a cable can safely conduct.  Besides the cross sectional area, other factors that impact the ampacity of welding cable are its length, ohm rating (i.e., resistance rating), temperature ratings of the insulation material and the ambient temperature. Shorter cables can carry more current than longer cables of the same diameter. Welding cable is often rated with a conductor temperature of 75°C (167° F), 90°C (194⁰F) or 105°C (221°F). While the copper wire itself can handle the high temperatures generated by higher amperages before sustaining damage, the insulation protecting them would melt. Welding cables are also often rated for an ambient temperature of 30°C (86°F). Higher ambient temperatures can reduce their ability to dissipate heat into the surrounding environment, and thus reduce their ampacity. In addition, several cables packed tightly together can also have a reduction in their ability to dissipate heat. Multiple cables should be slightly spread apart.
