3 Welding Cable Options in Order by Price

3 Welding Cable OptionsGenerally all welding cables are used for very similar applications. However not all welding cables have the UL or CSA approvals on them. Now that does not make these cables unsafe. It just means that as a consumer you need to make sure you trust the manufacturer. This way you’ll know you are getting a safe and quality product. The three main variations of welding cable are the Class K, the Class M and the Super Vu-Tron.

Class K

The Class K welding cable is made from 30 AWG copper strands. This is also known as the standard welding cable. It is not UL or CSA approved like some of the other classes of welding cables you can find. The cables come in black and red. Although there are other colors available upon customer request. Because of the copper stranded conductor as well at the rubber insulation of the cable they have good flexibility. They are used mainly for secondary voltage resistance welding leads as well as for power supply applications that do not exceed 600 volts.

Class M

A Class M welding cable has 34 AWG copper strands. This is to make the cable more flexible. The Class M cables are both UL and CSA approved. This kind of welding cable also comes in the same colors as the Class K welding cable. This variation of welding cable just like the Class K cable is very flexible. The Class M cable however is more flexible because it is made with even smaller copper strands. The cables have very similar temperature ratings as well as the exact same voltage ratings. What makes this cable more expensive is the fact that the copper strands are smaller making it more flexible. And the fact that this cable is both UL and CSA approved, while the Class K cables are not.

Super Vu-Tron

The super vu-tron welding cable is a Class M cable. It is a slightly different version made of the same 34 AWG copper strands. The super vu-tron has an orange colored jacket for safety. The orange color is a trademark of General Cable. The welding cable has a good abrasion resistance and is also weather and ozone resistant because of the special jacket that the cable has. The cable comes in sizes ranging from a 6 AWG all the way up to a size 4/0. The super vu-tron cables also have a temperature range of -50°C up to 90°C.

The welding cables are listed in order of price. The Class K welding cables are the cheapest and then working your way up the Super Vu-Tron cables are the most expensive. That leaves the Class M cables in the middle. Each cable is slightly different even though they are all intended to be used for generally the same thing.

Difference Between Type W and Type G Power Cables

The Type W and the Type G power cables are very similar. They are used for nearly the same applications. These are industrial strength power cables. The cables can be used on all kinds of job sites to give power to machinery. They can handle 2000 volts of electricity and have rubber insulation around them.  But there is in fact one main big difference between the Type W and the Type G power cables.


Each of these cables is a 2000 volt rubber power cable. They have thick insulation for industrial job sites. Both are rugged enough to be run over by trucks and dragged across rocky areas of job sites. This makes the cables not only perfect for jobs at home where that much power is needed but also for job sites. Industrial sites that require a lot of power may also require their cables to be rugged and durable because of the demanding and dangerous environment.

Type W Power Cable

Type W Power Cables Type W cables have no additional ground wires. There is a same size green wire in 3 conductor cables and higher. The different colors of the wires help to easily identify each wire. The Type W cables are made ideally for industrial to light to medium duty mining applications because of it heavy duty and durable rubber jacket. It also can be used for AC systems, mobile and portable electronic equipment. This rubber jacket on the cable can withstands severe environmental conditions, as well as exposure to oils, acid, alkalies, heat, moisture and most chemicals. This shows that this cable really can handle anything, allowing it to be perfect for messy and hazardous industrial settings.

Type G & G-GC Power Cable

Type G Power Cables Type G and G-GC cables include additional ground wires over and above their conductor count. If there are 3 main conductors there are also 3 smaller size ground wires. And if there are 4 main conductors then there are 4 smaller size ground wires. The “GC” stands for ground check. The G-GC cables are known for having an excellent resistance to impact. They are made with a cable core bound for superior flexibility and toughness. They are also made with a rope lay stranding to maximize the flex life of the cable.

The difference between the Type W power cables and the Type G power cables is the ground wires. The Type W cables do not have additional ground wires. While the Type G cables do. The wires inside the cable are both colored and have numbers imprinted on them to be able to tell what a conductor is and what a ground wire is. Other than the ground wires these cables are generally very similar.
