  • Induction plasma - Wikipedia

    The 1960s were the incipient period of thermal plasma technology, spurred by the needs of aerospace programs.Among the various methods of thermal plasma generation, induction plasma (or inductively coupled plasma) takes up an important role.. Early attempts to maintain inductively coupled plasma on a stream of gas date back to Babat in 1947 and Reed in 1961.

  • Is A Plasma Cutter Hotter Than The Sun? Or The Earth's Core?

    Dec 20, 2018  Plasma cutters are certainly a lot warmer than the average surface temperature on our Sun: around 45,000 degrees Fahrenheit (25,000 ° Celcius). The average temperature on the solar surface is 9,941 degrees Fahrenheit (5505° Celcius). So by calculation, a plasma cutter flame resembles roughly 4.5 sun surfaces worth of heat.
