What's the temperature range within the Plasma Arc Cutting (PAC) stream?

  1. 1,000-5,000°F

  2. 5,000-18,000°F

  3. 18,000-50,000°F

  4. 50,000-100,000°F

The correct answer is: 18,000-50,000°F

The temperature range within the PAC stream typically falls within the range of 18,000-50,000°F. The other options are incorrect because they either fall below or above this temperature range. Option A (1,000-5,000°F) is too low and would not provide enough heat to effectively cut through metal. Option B (5,000-18,000°F) is also too low and may not be able to effectively cut through thicker materials. Option D (50,000-100,000°F) is too high and may cause damage to the surrounding materials. Therefore, option C is the most accurate and appropriate choice.
