Arc OK intermitent issues on torch fire

Yes still same issue persisting. 20-30% of the time the arc will try to fire for a split second then pause and say invalid ArcOK signal. but ran mesh mode like what was suggested and didn't have one issue running 50 cuts. arcOK light was on solid on every cut. I can only thing there's a split second every now and then when the arcOk signal coming back is just that little bit to slow and it pauses itself due to no arcOK.

Is it "valid arc lost" or "no arc detected"

valid arc lost..

Try the following in yout connections.hal file:
you can adjust the time to suit, the above is 0.1 seconds.

Ok this is great my "valid arc lost" issue has been resolved i did 120 cuts no worries. Thanks everyone for the help with troubleshooting that issue

I then ran some actual cutting jobs and ran into this issue which was the other side to this topic,
Every now and then when it goes to pierce the metal it fires and blows the metal out but thinking it hasnt removed the metal due to no arcOK coming back it tries to start the arc again but the metal is already gone so its got noting to arc onto hence ruining the start point for that cut. >>

When that happens do you notice if the Arc OK led is lit on the GUI.
