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 colours). 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. The concept is similar to the flow of water through a hose. A larger diameter hose is needed in order to carry a greater volume of water. You use a smaller hose to water your garden, while the fire department uses a much larger hose to fight fires. 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 amperage 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 amperage. 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.
