6 Factors to Consider When Buying A Welding Cable

1. Ampacity
Determining the strength of the electrical current you’ll be using on a job site is a very important first step. Once you’ve got a range for the currents you will need, you can begin to shop for a welding cable based on its ampacity rating. Ampacity stands for “ampere capacity,” and the rating of various cables will narrow down your list of options considerably. This is probably the most vital of all of the factors to consider, since you absolutely cannot safely run higher currents through wires that aren’t built to handle it.

2. Insulation
The grade of insulation of a cable is also a determining factor on which cable you https://clicdanstaville.fr/choose. If your work environment is low-hazard, you might be fine with a more thinly insulated cable. However, if there is significant risk of moisture, chemicals, oils, or heat in your work environment, you will need to choose a cable with a strong insulation layer that is rated to be resistant to the hazards of your workplace. This is especially important when welding in marine and garage environments, where oil and moisture are commonplace. Both salt water and oil can erode standard grade insulation and lead to dangerous workplace conditions and tool failure.

3. Flexibility
You will no doubt need flexible cables if you are going to be working in tight spaces or at challenging angles. The downside of cable flexibility is that it is affected by both the insulation and the thickness of cable (which often determines ampacity). If you will be working in cramped spaces and have a need for flexibility of your cable, make sure you balance this carefully with your ampacity and insulation needs. Flexible, insulated cable does exist, but it might come with a higher price tag, so make sure you prepare for that possibility.

4. Length
Length of cable is another factor that plays against other important factors. The longer a cable is, the more resistance it will have. Therefore, longer cables have functionally lower ampacity. Don’t underestimate this factor; while it might be unnoticeable when switching between cable lengths of a few feet, it can have major effects over greater distances. Large projects using central generators that will be far from the site of the actual welding will especially need to be careful with such things.
