* When using a plate rider, use cutting height.
* When using a height control, the initial height may need to be reduced depending on the surface condition of the mate-
rial.
The published cut speeds are the result of ESAB's laboratory testing. The actual optimum and maximum cutting speeds may
vary based on material composition, surface quality (rust, surface scale or primers, etc.) and various user setup parameters.
