A 4/0 welding cable is thick and heavy. It has to be if you’re going to use it safely to perform high-intensity welding applications. It needs to be able to safely carry the voltage and current necessary to perform electrical welding.
This is true of any electrical cable. Exceeding the safe voltage capacities of an electrical conductor can be extremely dangerous. It will cause overheating and will increase the risk of electrical fires and electrical shock.
So it makes perfect sense why, in some instances, thick welding cables like 4/0 welding cables must be used if the job calls for them.
But there is another attribute that is highly valuable among welding cables – especially among the thickest and heaviest of them all.
Why Do Welding Cables Need to Be Flexible? So let’s say you have a heavy gauge building wire, also rated to 600V, just like many welding cables. You might be able to subject them to the same voltage load without danger.
The difference is, once installed, the building wire isn’t going anywhere. It just sits in place and communicates a flow of electrical energy to lights, systems, and other appliances.
The welding cable is not like that. It doesn’t get the luxury of a sedentary job. Welding is performed at job sites, often outside, on construction sites, and in industrial settings. The welder and his equipment need to work on-site, on-location.
That is, the welding cable must not only be able to handle the voltage load but also be flexible enough to be bent or maneuvered into location. If not, it would be impossible (or at least very difficult) to complete a job.
In order to accomplish this high degree of flexibility, many manufacturers create their welding cables with exceptionally high conductor counts.
Take, for example, the 4/0 welding cable available for sale online at EWCS Wire (EWCSWire.com). The nominal diameter of this flexible welding cable is only .72”
Now get ready for the conductor strand count. It’s made not with 1,000 strands, not even with 2,000 strands – but with 2,014 strands of 100% copper conductors.
The higher the strand count, the thinner the individual conductors must be. That way, the wire can be made substantially thicker and heavier (giving it the ability to tolerate a higher voltage load) while allowing it to remain relatively flexible.
Where to Get Extra Flexible 4/0 Welding Cable As stated, EWCS Wire carries a wide range of flexible cables, including 4/0 welding cable. These cables are made with very high strand counts which makes them highly flexible and suitable for electric welders in a wide range of industries.
In addition, there are a number of other features that make these cables suitable for other purposes as well.
They are insulated with heavy-duty EPDM insulation, which is resistant to ozone, UV, and weathering. This makes them viable as photovoltaic cable, or PV cable, which is used in solar arrays.
In addition, they are also abrasion-resistant as well as oil and gasoline resistant. Consequently, they can be used as leads for motors, generators, and more. Their flexibility makes them suitable as battery cables, too. For this reason, black and red insulation is used on these cables.
In addition to welding cables, EWCS Wire also sells marine battery cables, tray cables, instrumentation and fire alarm cables, building wires, bare copper ground wire, and a wide range of other specialty electrical wires and cables.
