There are many different types of welding cable, and cables in general, available from both hardware stores and online specialty stores. It goes without saying that it is essential to research the exact right kind for your needs before you buy. This quick guide should help you to locate the correct welding cable for your project:
Length
The right size cable is an important consideration in terms of both length and width. A cable long enough for where it is being fitted is only one consideration when it comes to welding cable. The shorter a cable is, the more current it can carry, even if it is the same width as a longer cable. Therefore, you must also consider the output of your welder and which length of cable will be able to handle it.
Durability
The advantage of 2/0 welding cable is that it is much more flexible and durable than other types of cable. It is still worth choosing a high grade cable that will retain its quality for a long time. Worn or frayed cables won’t work as effectively and in the worst scenarios, can cause a fire hazard, an important consideration given the conditions that welding cables are usually used in. Choosing the best quality cable combined with proper maintenance will prevent any dangerous mistakes.
Ampacity
2/0 cable typically has a high ampacity and heat resistance, but considering that high ampacity causes cables to heat up more, a high insulation capacity is also essential for safety purposes. The cable length and type of machine it is attached to will also have an impact on this, with longer cables having lower ampacity ratings.
Use this guide as a starting point and consult with hardware specialists if you are still concerned. This way, you are guaranteed to find the exact right cable for your job which will also be safe.
