THCAD-10 Mode was created by little_sparky
Hi All,
Super quick question. I just really want to be sure, using a THCAD-10 with plasma C, is this mode 0 or 1?
(0=Use external arc voltage in to calculate Arc Voltage and Arc OK or 1= Use external arc voltage in to calculate Arc Voltage, Use external arc ok in for Arc OK)
And if its 2 then I have been up way past my bedtime haha
Thanks in advance

Mode 0.
Mode 1 needs two more wires to plasma power source for arc ok from it. If it does not have the pins for that ( no CPC port on the plasma ) that will require more wiring and a reed relay or an induction coil with a normal relay to be added to plasma source.

I have Hypertherm 45 with ArcOK output on the cpc. I can use either mode 0 or 1 but choose to use mode 0 now. I am thinking of swapping to mode 1 to see any difference. Is there any benefit of using mode 1 over mode 0?

Not really, it just takes a bit of trial and error to find reliable min and max values for the ARCOK. It does work perfectly well with most plasma sources.Is there any benefit of using mode 1 over mode 0?

I think it would be foolish to use a Synthesized ArcOk (Mode 0) on a machine that has an ArcOK signal provided (eg is designed for CNC use).
Remember that a Plasma cutter with ArcOK will have its own logic outside of the CNC controller in relation to arc restarts etc which is intertwined with the ArcOK signal management. So by using a synthesized signal, there is a high probability the two systems will get out of step with each other as you are not using the plasma device in the way in which the manufacturer intended. One symptom of this I have observed might be cutting dotted lines becasue the CNC machine is moving when there is not a valid arc because the machine turns off the arc (and ArcOK) and attempts a restart.
