Well we are still fighting the divots and the main issue of having to cut at reduced feedrate to avoid it from just gouging the plate. Here is what we have tried to far:

Add a large air condenser
Motorgaurd's top of the line filter/sep system
Gauge at the back of the cutter to monitor psi
New Powermax85 cutter
Some torch, but we did try a new torch briefly with the same results
All new torch end parts (retainer, o-ring, electrode, etc...)

Anymore advise is appreciated.
