Therefore, you should choose copper-core welding cables for heavy jobs. Therefore, welding cables that have a copper core are generally more heavy-duty and offer more conductivity. In comparison, copper turns out to be a better electrical conductor than aluminum. Thus, the core of a welding cable directly affects its performance in various welding jobs. As the strand count of the core increases, the flexibility as well as the conductivity of the cable increases. The core of a welding cable basically contains hundreds of layers of electrical conductors such as copper or aluminum. Copper Core vs Aluminum Core Welding Cable When you are buying a welding cable, there are 2 factors that you need to carefully think about which are the core of the cable and the insulation coating available on top of the core. But, the cable should also bend easily without permanent deformation so that the welder can easily move it around as required. A welding cable should be strong enough to avoid wear and tear so that its insulation layer would not get damaged during welding. Welding cables are also commonly called welding leads and the function of these cables is to attach the ground camp as well as the electrode to the main power source.Īs for the important qualities of a welding cable, the factors that affect its performance the most are the flexibility of the cable and its reliability according to the job. EWCS 2 AWG Cable – Made in the USAīefore we start discussing the characteristics and qualities of a welding cable, let us try to understand what a welding cable is first and how it differs from other welding accessories. Different Types Of Welding Cable Insulations

In this guide, we will be covering everything that you should know about welding cable and even offer some quick buying options to get you started. So, we have prepared this helpful guide that revolves around welding cables. However, finding the perfect cable size for the job is easier said than done. The perfect welding cable for the job will ensure a safe welding practice while keeping the welder safe from electrical accidents. To avoid all of that, it is crucial to find the right welding cable for the job. And since welding requires high voltage input, a burnt insulation layer can lead to fires caused by short circuits. Not only will it affect the welding performance, but it can also cause some severe problems like overheating and causing the insulation to burn out completely. If you, unfortunately, end up with the wrong type of welding cable for the job, it can turn out to be quite hazardous for the welder. There are many different parameters of a welding cable that can create variations in the end results such as the size of the cable, length of the cable, type of cable, etc. There are a lot of variables to think about before you could start welding and one of the most important ones is the welding cable. Welding is a rather complicated process and one has to put a lot of hours into the job to understand the core parameters and specifications of the machine to be able to create perfect and reliable welds.
