Skip to content Russ follows up the previous cutting tests by separating the optical effect from the chemical and mechanical effect of airflow. The session explores why different air-assist conditions can create very different cuts even when focus, speed and power stay the same.

What You’ll Learn
- Why flow through the cut influences the carbonised reaction zone.
- Why pressure alone is a poor description of useful air assist.
- How airflow can remove debris, alter heating and change cut depth.
Air Assist Is Part of the Reaction
Russ treats the cut as a coupled process involving energy absorption, carbonisation, hot gases and material removal. Changing the flow changes that environment and therefore changes the final result.
Flow Matters More Than a Gauge Number
The useful quantity at the cut is the movement of gas through the nozzle and kerf. A quoted pressure figure does not by itself tell you what flow reaches the material or how effectively it clears the reaction zone.
Why This Session Matters
It turns air assist from an accessory setting into part of the cutting mechanism itself.
