When it comes to electrical cables, welding cables are one of the most flexible varieties on the market. These cables are not only able to handle high voltages, but they are extremely resilient and flexible. Although they were originally designed for welding, the sure and tough construction of these cables makes them ideal for any number of high voltage applications. If you need the highest quality cables, you need to check out our inventory for the best welding cables for sale online.

Here at EWCS Wire, we are dedicated to proving our customers with the best wire and cable options. We know that whether you are wiring professionally or you just need a special cable for a project, having quality conductors is crucial. That’s why we take such pride in offering our customers the best options for every job.

So what exactly is welding cable? Simply put, a welding cable is an extremely flexible length of cable designed to handle high amperage and up to 600 volts. While these types of cable can serve a multitude of functions, they are most commonly used for welding, as their name implies. This is because welding requires a conduit in order for the extremely high current electricity to be transferred to the electrode.

Welding machines generate a large amount of power. When the positively charged electrode contacts the negatively charged workpiece, this high current exchange creates enough heat to melt the metal electrode and fuse the workpiece. Without a quality welding cable, the connection between the welding machine and the electrode would quickly overheat and fail.

Like any cable, constructing good welding cables begin with copper. Copper is an ideal material for wiring because it is such a fine conductor of electricity. Despite this fact, copper does have some electrical resistance. This means that it will heat up while in use, especially when handling the high currents from a welding machine.

In order to ensure flexibility, the copper in your cables has to be stranded. Welding cable is part of a tool, and without high levels of flexibility, it severely limits the usefulness of that tool. If you wanted to weld using a solid conductor cable like home Romex wire, the lack of flexibility would quickly result in cracking and eventual failure. To give welding cables their flexibility, finely stranded copper is used to make the conductor. Because these stranded conductors have to handle so much current, they require large strand counts. Our thinnest welding cables contain 259 copper strands, while our largest cables contain 2014 strands.

To protect all of those fine strands of copper, good welding cable requires some sturdy insulated jacketing. The insulator on welding cables has two main functions: keeping the conductor contained and resisting the common corrosive materials found in workshops across the country. Without sturdy insulators, materials like gas, oil, or even coarse surfaces could quickly eat through your cables and expose the conductors. Here at EWCS, all of our welding cables for sale feature ethylene propylene diene monomer(EPDM) rubber. This resilient rubber will help you avoid corrosion and it rated to tolerate conditions ranging from -50 °C to 105 °C (-58 °F to 221 °F).

When you’re looking at our welding cables for sale, it’s important to know what you’re looking for. Whenever you are dealing with high voltages and high amperage, you need to be sure that the cable you purchase is suited for the job. Trying to push high current electric through too a small cable would be like trying to hook up a drinking straw to a fire hydrant, it just won’t work and you might even get hurt. Research your application before you buy welding cable to ensure you purchase the correct size.

All of our cables are sold based on AWG sizes. These sizes increase as the diameter of the wire gets smaller, meaning a size 4 is smaller than a size 2. Sizes above zero notated with multiple zeros or a number/0, i.e. 000 would be 3/0. This means that our 6 AWG wire is our smallest size at 0.320” in diameter. We offer welding cable for sale in sizes 6-4/0 and are available in black, red, green, yellow, and blue depending on the size. We also offer our 2/0 welding cables with built-in Lenco connectors.

So if you are looking for welding cable for sale, look no further. Here at EWCS, we are proud to offer the best extra flexible heavy-duty welding cables online. Whether you’re using these cables for welding or for some other project, we know that you will love the quality and resilience of our cables.
