What is Plasma Cutter?

We all saw plasma cutter going through metal like a heated knife through a butter. Plasma cutter is powerful tool for metal cutting, but how does it work? What is plasma cutter?

What is plasma cutter?

plasma is the fourth state of matter after gas. Webster’s Dictionary defines plasma as a ”collection of charged particles ... containing about equal numbers of positive ions and electrons and exhibiting some properties of a gas but differing from a gas in being a good conductor of electricity...”. To simplify it, plasma is an electrically heated gas stream.

This same logic and physics is used in plasma cutters. Plasma cutting works by passing a super-fast jet of hot plasma through (conductive) metals to cut through it by melting it. Plasma cutters create plasma using a gas (such as argon, nitrogen, oxygen, or combination) through which an electric arc is passed. In this process plasma jet torch can reach temperature up to 50000 °F! And while some plasma cutters are big, industrial, robotized machines surrounded by guard box and similar heavy-duty safety features, the most common plasma cutters are handheld devices (without any specific guard) that are operated manually by operator’s hand control.
