What is the approximate temperature produced by the combustion of oxygen and acetylene during oxy-fuel gas cutting?

1. 3500 F

2. 4500 F

3. 5612 F

4. 6000 F

The correct answer is: 5612 F

The temperature produced by the combustion of oxygen and acetylene during oxy-fuel gas cutting is approximately 5612°F. This high temperature is critical for the cutting process, as it allows the torch to reach the necessary heat levels to melt and oxidize the metal being cut. Acetylene, when combined with oxygen, creates a flame that is among the hottest of gas flames, enabling efficient cutting of various materials, especially steel. The exact temperature can vary slightly based on mixture ratios and environmental conditions, but the value of 5612°F is widely accepted in the field. Understanding this temperature is crucial for safety practices and equipment specifications during cutting operations.
