A suitable welding cable is an important element of the welding rig, just like the welding gun or the welder. Welding requires a high amount of electric current to be carried from the electric source to the working electrode, and there’s also the work cable that carries current from the source to the work clamp.

That is why you will need welding cables for completing your entire welding circuit. 

Best Welding Cable

Depending on various factors like- distance from the source, circuit length, rated output, duty cycle, etc- you will need different types and sizes of welding cables. This means one needs to understand which type/size of cable to buy for doing their jobs without any hassle.

Choosing the perfect welding cable for your rig can be a challenging job. But we are here to make that job easier for you because we will give you a complete guide on how to choose the perfect cable for your desired job. We will also suggest some of the best products out there on the market for you to consider.

Welding Cable Specifications Guide

AS with any product you buy, there are many important specifications to consider while buying welding cables too. The most important specifications are:


We have already given an in-depth guide to what gauge ratings mean above. If you are looking for a longer cable, then you need relatively thicker gauge sizes that will minimize resistance. If your welding circuit is short, however, you can go for a thinner gauge.


Length usually refers to the total length of your welding circuit, meaning the total path that electricity travels. But as a general rule of thumb, your cable length should be enough so that it can reach every corner of your welding space. 

Keep in mind that you need one cable to connect the welder to the electrode, and another cable to connect the welder to the work clamp. Another important piece of information to remember is that electric resistance will increase proportionally with the length of the wire.


Ampacity is short for Ampere Capacity. You can understand what it means from the name itself. Ampacity indicates the maximum amount of current that your cable can handle safely. Ampacity increases as diameter increases, which means wires with high AWG ratings(4/0,3/0, etc.)  have the highest ampacity. Depending on your desired job, the required ampacity will be different.


Welding cables carry lethal current, and that’s why it’s necessary to insulate them with proper material. Common insulators of welding cables are made of EPDM, neoprene, and PVC. Neoprene and EPDM both types of insulation jackets are flexible while being corrosion resistant at the same time.

The only downside to these materials is that they are not appropriate for exposure to gas and other petroleum-based liquids. PVC is much less flexible than the two but has a very high resistance to corrosion, cuts, and tears.


Aside from the Insulating material, flexibility depends on the strand count. The higher the strand count, the more flexible the cable will be.


Additional insulation colors might help you to distinguish between different cables.

How to choose the right Welding Cable?

When you are trying to select the perfect cable size for your welding rig, choose the cable that handles the maximum output that you need. There are three most important factors that you need to keep in mind while doing that:

  1. The total length of the welding circuit
  2. Rated output
  3. Duty Cycle

The welding circuit is the total path that electricity will travel through. In a typical welding circuit, the electricity will go through the power source, electrode cable, work clamp, electrical arc, work clamp, and work cable.

As mentioned before, your welding cable should be able to reach every corner of your welding space. Thicker gauges are recommended for longer circuits, while shorter circuits can work best with thinner gauges.

The rated output of the power source means the maximum amperage level at which the machine is meant to be used. However, some power sources can produce higher amperage levels than their rated output for short periods.

The rated output level of a machine is normally included with the machine’s name, i.e, “Idealarc 250” means 250A rated output.

The duty cycle is a capacity rating of a welding power source. The duty cycle is the percentage of a power source that can operate at a certain amperage level for 10 minutes without exceeding its thermal limit.

If the output level is decreased, the duty cycle of the power source will be increased until it reaches a 100 percent continuous output. You can find the duty cycle ratings on the power source’s nameplate or the user’s manual.

The duty cycle of a welding power source is usually associated with the welding process in which it will be used. It also depends on whether the machine operates off of a single-phase or three-phase power.

You will usually find a chart from the cable manufacturer that will help you to select the right welding size for yourself using the three factors mentioned above.

Welding Cable Size Guide

Welding cable size is measured in North America in the American Wire Gauge(AWG) system. It is a logarithmically stepped and standardized wire gauge system that measures the cross-sectional area of each gauge.

The cross-sectional area of a gauge is the most important factor for determining how much current a certain gauge can carry. The unit that indicates the current carrying capacity of the gauges is named Ampacity (Ampere Capacity).

According to laws of physics, a larger cross-sectional area of a conducting wire means it will have lower resistance and will allow more current to flow than wires with a relatively smaller area.

For our purposes, the AWG number or the gauge number of a certain wire will determine a standardized diameter. Increasing the gauge number will denote decreasing diameters of wires. The AWG tables are for a single, solid, and round conductor.

The AWG of a stranded wire is determined by the cross-sectional area of the comparable solid conductor. A stranded wire will have a bigger overall diameter than a solid wire because of the small gaps between the strands.

The AWG numbers start from 0000 AWG or 4/0 AWG, which is defined as 0.46 inches in diameter, and the numbers go up to 40 AWG which is .0031 inches in diameter. You could even determine values for higher AWG numbers but we are only going to stick to what’s available on the market. The numbers are determined from this formula.

AWG ratings for welding cable sizes will usually have three numbers- 1. Overall rating, 2. The number of strands, 3. Rating of a single strand. Our first product in the following list has a  size of 2 AWG 624/31.

This means that the wire has a total cross-sectional area of 2 AWG, made from 624 strands rated at 31 AWG. For your convenience, we have included a chart that will help you determine what kind of welding cable you need for yourself.
