How Hot Is a Plasma Arc

The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emanating from the nozzle. The temperature of the plasma is in excess of 20 000°C and the velocity can approach the speed of sound.

How hot does plasma get?

Naturally occurring plasmas can reach temperatures of up to 106eV (1eV ~ 11600K) [1], in industrial ap-plications maximum temperatures lie around 1eV [2].

Is a plasma cutter hotter than the sun?

The heat of a plasma cutter can reach an impressive temperature of 25,000 degrees Celsius. To put this into perspective, it is hotter than the surface of the sun which sits at a comfortable 5,505 degrees Celsius.
