A welding cable refers to electric cables that supply power between both automatic and manual welding equipment and the welding tool used on construction sites. Welding cables are designed to carry high currents even under demanding usage conditions and are known for their durability and flexibility in Singapore. A welding cable is constructed by wrapping a series of copper hairs inside a resilient and non-conductive jacket that can withstand the continuous movement over rough surfaces.
Also known as ampacity, the current-carrying capacity of welding cables is calculated differently as compared to other cable types. Ampacity is the maximum amount of current a cable can carry without going over its operating temperature rating. Other than the ampacity, other factors that have to be considered when choosing a welding cable include the duty cycle, output power and circuit length. The duty cycle refers to the capacity rating of the welding power source and can be found in the manual provided by the manufacturer. The output power will determine the maximum amount of current that can be used when the welding machinery is operating and will affect the size of the cable needed. The circuit length is the entire path the electricity will travel through the welding equipment and is important as it influences ampacity. A longer length will have more resistance, resulting in the ampacity rating decreasing.
The welding cable should be sized according to the specifications, as an incorrect size can result in hazards happening. Cables with a diameter that is smaller than required will increase the chances of a fire risk, as the welding cable will heat up, potentially causing the insulation jacket to be damaged. Welding cables should also not be larger than required, as they do not help to conduct electricity more efficiently, and is more expensive than needed.
