I have a Crossfire Pro with a Razorweld 45.

0.063 cut height
0.5 sec delay
16 ga steel
The machine pierces and cuts fine but the initial part of the cut (first inch or so) as a narrower kerf than the rest of the cut. Thisleaves a bump on all the cut edges around the lead in and lead out. The remainder of the cut has a fairly consistent kerf width.
