I have a Crossfire XL with THC using a Razorcut 45.
I was cutting Robert Stadelmaier’s (Robert Stadelmaier | FireShare | Langmuir Systems) horse welcome sign from Fireshare and got some scoring marks in the middle of the piece today I hadn’t seen in a previous cut.
The full size sign with the scoring marks was on 14ga and the clean, reduced, version on 10ga. Based on the Razorweld cut chart I used 40amps for both cuts though it appears that 40 was really too high a setting for the 14ga. They were cut on different days with the 10ga piece cut first.
Any advice on what could have caused the scoring? Do I have a functional problem, signal interference on the control lines to the plasma cutter, just too high an amperage for the cut?
