Arc OK intermitent issues on torch fire

Notice the "time delay" in the pdf, those are slow acting fuses, for electronics use always fast acting ones, they are usually made of see through glass with a very thin wire inside.

The derived arcok from THCAD works perfectly although i am sure there might be situations where it might fail but not due the the way it works but due to how plasma sources work.
The reed version has no way of failing if done right as it relies on a big amount of current passing through that wire.
By now i have 4 machines using the derived arcok from thcad and they never failed, but that needs a bit of tweaking, roughly setting the low limit to 60-80V and the high limit to 250V and then gradually lowering it till it starts failing or till it reaches 140-160V and leaving it there. That will prevent the machine getting the arcok in case the torch has fired and it is to high so the current passing through it will be low and the subsequent voltage will be anything from 180 to 280 or more V, causing the plasma to fail the arc as it can not be transferred to cutting power.
Or to put it simpler it MIGHT give arcok even when not cutting at full power in such case. The above tweaking prevents that.
The low side is less important as that would be the case when the torch is very low or touching the material hence the voltage will be low but it will not impede the cutting process, it will just mess up the nozzle.

I have NO issues at all with synthesised ArcOK.
