Problem, please help
I'm new to plasma CNC. Previous employee just up and left so I've been thrown in the deepens. Everything has been going well, been cutting mild steel, aluminium and stainless steel in various thicknesses.
Suddenly yeaterday mid-cut the plasma head started lifting away from the cutting surface, still arcing but about an inch above surface.
Went through process of replacing electrode, tip and swirl ring. Cleaning sensors and water traps. Shut down system and restarted everything. Tried different cut files and different metals.
Torch pierces metal and then lifts one inch away from surface over the next 2 inches of cut.

I know it isn't great equipment, but it is what we've got.
