Are you looking for the answer to ‘what size wire is welding cable?’ Then you have come to the right place!
Welding cable is a highly specialized form of electrical cable that is used in welding. While the welding cable can range from 6 AWG to 500 kcmil in size, the most common sizes used are 2 AWG to 4/0 AWG. This relatively thin cable is designed to provide superior resistance to high temperature and superior electrical conductivity, making it the choice for a variety of welding and electrical applications.
In the United States alone, an estimated 2 million tons of welding cable is used each year, with the global market estimated to reach USD 12 billion by 202
So, if you are in the market for welding cable, keep reading to learn more about what size wire is welding cable?
What Size Wire is Welding Cable?Welding cable is essential for any type of welding job; without it, you won’t be able to get the power where it needs to be. But choosing the right cable can be tricky.
What size wire do you need?
Types of Welding CablesWelding cables come in two types: flexible and rigid.
Flexible welding cables make it easy to move around during a welding job. Rigid welding cables provide a permanent wiring option, great for longer-term fixtures.
Wire Gauge and Amp RatingsThe wire gauge and amp rating indicate the amount of power the welding cable can handle. The wire gauge measures the cable’s thickness, from 6 to 4/0. The higher the number, the thicker the cable.
The amp rating, expressed in amperes (amps), indicates the maximum current the cable can handle. The higher the amp rating, the more current the cable can handle.
Cable Size for WeldersThe size of cable you need depends on the type of welder and the amount of amps it uses. A MIG wire welder requires a cable between 4 gauge and 2/0 gauge, while a TIG welder needs a cable between 4 gauge and 1/0 gauge. For stick welders, you’ll want a cable that’s 2/0 gauge or thicker.
A good rule of thumb is to choose a welding cable with a gauge twice the size of your welder’s maximum amps. For example, a welder with a maximum amp rating of 250 will require a 2/0 gauge cable or heavier.
