Welding cables are used in electric arc-welding machines to charge an electrode which in turn is required to produce an electric arc, or any heat source between the electrode and the metals, or other materials which are being welded. In other words, welding cable is an electric conductor for the welding electric current. It comprises of of fine copper strands which are clustered together inside a non-conductive durable jacket, made from synthetic or natural rubber of various colours. These fine strands provide more flexibility to the welding cable than the other electric conductors while the insulating jacket provides repeated movements of current through the rough surfaces. The flexibility of the copper strands should be such that the diameter of the copper strands should increase with the current level. Contact the leading welding cable manufacturer for selecting the cable for your project, however check for the below details.
