  • What kind of gas is used in plasma arc cutting?

    In conventional plasma arc cutting, the plasma cutting equipment includes the plasma torch assembly, which utilizes a single plasma gas serving as both the ignition gas and the cutting gas. Typically, the standard process employs nitrogen, oxygen, or a hydrogen-argon mixture.

  • How is a plasma torch used to cut metal?

    The resulting stream can melt and blow through most metals quite easily. That’s a plasma torch. Plasma cutting torches usually use a copper nozzle to constrict the gas stream with the arc flowing through it. That arc jumps from an electrode in the torch to something else – usually the conductive material being cut. That’s a ‘transferred arc’.
