Does anyone know the current (amps) rule of thumb for TC ?3/8" plate seems to cut only very slowly and with lots of pure TC dross(dross length=material thickness) at 40amps, much faster, say 10-12" minute at 60 amps with dross length=1/4 material thickness max. This stuff is wierd to cut. It melts producing pure TC drossless dross. Hell to grind. Its not supposed to be a great heat conductor like copper, so why is it so resistant to plasma cutting? Also, I havent cut copper yet, so what can I expect with 110 copper plate, will it cut differently? Hopefully easier. Thanks.
