What is the minimum number of orifices in a cutting tip?

Explanation:
The key idea is that cutting relies on a focused jet of gas being delivered to the workpiece. That jet comes through a single central opening in the tip. The other small holes around the tip are used to preheat the metal and sustain the flame, but they aren’t required for the cutting action itself. So the smallest, simplest cutting tip still needs just one orifice to perform the cut.
