About Welding Cable
This page offers flexible copper welding cable which is a rubber insulated cable used to hook up welders in shops and garages. Industrial grade welding cable has UL, CSA, and MSHA approvals and a more rugged jacket to handle more impact each day.
Our welding cables are made with 30 AWG copper strands for added flexibility. Common AWG sizes are 6, 4, 2, 1, 1/0, 2/0, 3/0, and 4/0. Welding cable is a portable power cable commonly used for power supply applications and secondary voltage resistance welding leads.
Welding Cable Information
Welding cable is one of a kind cable because its term means what it means. If you wanted electrical wire you would need to answer about 5 more questions before finding what you need. You could be looking for THHN wire, Romex®, UFB cable, and even service entrance cable. They each have their own function for different applications.
If someone called looking for welding cable the only thing you would need to as them is how flexible they want it. The standard welding cable is already very flexible compared to electrical wire or power cables and some people don’t realize that. The flexible welding cable comes in an orange jacket and it’s called Super Vu-Tron welding cable. It has smaller strands that make the cable more flexible and it has a more rugged outer jacket to protect against daily industrial damage. This cable is used on job sites to very large welders or as a power cable supplying power to generators and industrial machinery. This type of welding cable is run over and dragged around each job site so it needs extra protection.
You definitely can’t confuse it with battery cable. Battery cable doesn’t need to be made flexible or tough because it was made for a different application that doesn’t require that. Battery cable also has a PVC jacket which doesn’t compare to the welding cables rubber jacket. You will find that the battery cable is much cheaper and when you receive it you will see why.
If you need something with a high voltage rating you should look at a DLO cable (Locomotive Cable). It is a little bit less flexible but it has a 2000 Volt rating instead of the welding cable 600 Volt. The Type W power cable also has a higher voltage rating and it comes in multi-conductor as well. Type W is like an industrial-size extension cord used in very high power applications.
Welding Cable Information
Sometimes people call us and all they know is the AWG size of the wire or cable that they need. So we start asking questions to figure out what you might be looking for. The first thing we ask is if it’s an electrical wire or a power cable. If they’re unsure of the answer then we start questioning the application. Most types of wire and cable provide the same amps based on the size so we have to figure out the right insulation for the situation.
If it’s going outdoors and you’re putting it in conduit then you’ll need the electrical wire called THHN wire. If you need more than one conductor then we would suggest running 2 THHN wires or a tray cable. The wires inside the cable are the same as the singles wires but wrapped together for easier installation.
If you needed something for your welder or garage then I would recommend a welding cable or even a flexible welding cable. It has a rubber jacket which is made durable for being banged around the garage or shed areas. It’s tough enough to be run over, walked over, and even dragged on concrete. PVC insulation on the electrical wire isn’t made very durable because it isn’t needed for the application. It’s being put in conduit for the life of the wire which might come across some water and oil. So the THHN wire was made with a nylon coating for just that.
Welding cable is usually always just a one conductor cable. There’s a portable cord or SO cable that’s similar but still a little different. SOOW cable is just like an extension cord that has indoor jackets, outdoor jackets, and extreme weather jackets. All of the different power cables are priced based on the amount of copper and then the type of insulation. The insulation comes into play a lot more with pricing power cable because of the amount of rubber. The electrical cables only have cheap PVC insulation so it’s easier, quicker, and cheaper to make.
3 Manufacturers of Welding Cable
1. General Cable
General Cable is a well-known manufacturer of all portable cord and industrial power cables. A portable cord has rubber insulation and it connects power to portable machines like generators and power tools. Welding cable is used to bring power to a welding machine and it’s flexible so that the machine can move around the shop with ease.
General Cable offers black and red welding cable with MSHA and RoHS approvals. They also make an upgraded (more flexible and durable) Super Vu-Tron Cable in orange with a UL and CSA approval as well.
2. Coleman Cable
Coleman Cable focuses on PVC hook up wire and portable cord cables. Coleman manufactures black and red welding cables that are MSHA and RoHS compliant as well. However, they do not offer a Super Vu-Tron cable because it’s a registered trademark owned by General Cable.
3. Alpha Wire
Alpha wire focuses on electronic computer and telephone cables with very efficient shielding options. However, they are very large and have grown into new markets including portable cord and welding cable. The Alpha Brand welding cable will be more expensive but Alpha has quality as a number one initiative and their price will reflect it.
UL Approved Welding Cable
Standard Welding Cable
Standard welding cable is not UL or CSA approved but it is MSHA and RoHS approved. Typically, welding cable is used by homeowners and small shops to supply power to a welder or small 600-volt machine. The cable has protective insulation so that it doesn’t rip or tear when being dragged along the shop or garage floor.
UL is Underwriters Laboratories and they are in business to double-check the attributes that are listed on wire and cable. Therefore, UL tests and approves the Super Vu-Tron welding cable to perform to the standards that are presented on the spec sheet. Super Vu-Tron is an upgraded welding cable mostly used in industrial applications supplying power to larger machines that also require more protection.
