What Are Welding Cables Made Of?

Welding cable contains one finely stranded conductor surrounded by a nonconductive rubber covering. This insulating jacket is quite durable and resistant to overheating, burns, sparking, and physical abrasions. The internal strands are usually made of copper, making them more flexible than other types of wiring.

Can You Use Welding Cable for Battery Cable?

Yes, welding cable is compatible with battery applications, so you don’t necessarily have to use a battery cable. Most manufacturers produce battery and welding cables with the same ampacity at the same sizes.

Because welding cable can tolerate temperatures between -50℃ and 105℃, this makes them perfect for battery use. In fact, their fire retardance is superior to that of battery cables (UL 1581 vs. UL 553 and 558). Welding cable is also better for large battery banks as used in manufacturing since they come in a larger range of sizes than battery cable. However, both types of cable are effective in resisting the effects of cuts, grease, and oil.

How to Choose the Right Welding Cable

Before deciding on a welding cable, you’ll first need to consider what size is best for your needs. To determine this, find out how many amps you’re using in your current work. Choosing one that’s too small could present a fire hazard due to generating too much power in a small area; and getting one that’s too big will cost you a lot of money.

When you’re welding, find out the total length of your welding circuit, or the path by which electricity runs as you weld. This includes the welding machine itself, as well as the gun/electrode holder, wire/stick electrode, work cable, and work clamp.

Then, find the maximum amperage on your machine. Once you have that number, you’ll also require the capacity rating, or how much current you’re able to use before your cable overheats and turns off. This number is based on the percentage out of a ten-minute period and can be found either in the owner’s manual or on the side of your machine.

Now you have everything you need to pick a cable. Keep in mind that the American Wire Gauge (AWG) sizes go up in number as the diameter gets smaller. Common sizes include 4/0, 3/0, 2/0, 1/0, #1, #2, #3, and #4.
