Now that we’ve learned all about plasma, it’s time to learn how the fourth state of matter cuts through metal like butter.
First, a pressurized gas is sent through a small channel with a negatively charged electrode. When the power is turned on, and the tip of the nozzle touches metal, a circuit is formed and a powerful spark is generated. This spark heats the gas until it becomes plasma, moving at 20,000 feet per second, which melts metal to molten slag.
Check out some of our plasma cutters in action below!
