When cutting with a torch, where is the hottest part located?

When cutting with a torch, the hottest part of the flame is located just past the tip. This area is referred to as the "feather" of the flame, where the most intense heat exists. The flame produced by the torch has several zones, and while the tip does emit heat, it is where the gases mix and combust that the highest temperatures are achieved. As the flame extends outwards beyond the tip, it reaches a peak temperature ideal for cutting through metal. Understanding this helps ensure effective and safe operation of the torch, as utilizing the hottest part of the flame is crucial for efficient cutting.

The flame's base and center do generate heat, but not to the extent of the feather region, which is specifically designed for optimal cutting performance. The focus on the area just beyond the tip is essential for achieving clean cuts in the material being worked with.
