A plasma torch is provided, comprising a first electrode holder configured to be received by the plasma torch and adapted to cut a thinner workpiece. The first electrode holder is configured to receive a first electrode assembly comprising a holder element having an emissive insert element received therein. A second electrode holder is also configured to be received by the plasma torch and is adapted to cut a thicker workpiece. The second electrode holder is interchangeable with the first electrode holder, with respect to the plasma torch. The second electrode holder is further configured to receive a second electrode assembly comprising a pencil element. The interchangeable first and second electrode holders thereby allow a single plasma torch to cut both the thinner and thicker workpieces. An associated electrode system and an electrode device are also provided.
