In 1/8 aluminum holes what would be your speed at 45? In smaller holes there is not enough distance to accelerate to faster speeds so with smaller holes there is a maximum speed it can cut no matter how fast it is set. Acceleration takes time and distance to reach full speed.
This chart shows turning Amps down a lot at faster speeds for thin aluminum.
I am curious if any with Hypertherm 45 sync with fine tips can say if these holes would be improved.
