Hi @moonshinefabworks we’re very confidant that what you are seeing is the noise problem that we’ve been discussing above. If you scroll up you can see my update to this thread today where we mentioned that as a precaution we are going to send out a snap-on ferrite choke to every CrossFire PRO owner that already has received their Box 2 so that they can solve this issue for good. We are going to start shipping these out early next week via USPS. In the meantime, the easiest way to prevent it for your setup is to move your plasma cutter away from the electronics enclosure as far as you can and also unloop any cables that you have including the work clamp and torch cable (loops in these cables can magnify the noise).
