Arc OK intermitent issues on torch fire

It is looking more and more like an issue in the machine then.

Do they use a mechanical relay?

From what i got back from them yes its a dry contact mechanical relay.

OK, if not I was going to suggest swapping 12 and 14 to reverse the current direction in the machine.

Seeing as you have checked all the wiring and connectors, I have run out of ideas...

might try that anyway cant trust what they say half the time. If not i might do a dodgy and pick up a new machine from a tool shop hook it up and see if i am having the same issue or not, then return the machine.. lol
Then just send mine off for repair or whatever they want to do.

Again, lower the pierce height.
Try 3 or 2.5mm, see if that happens again.
If the torch is high it can not reach the threshold to activate the arcok signal, although the arc is established and cutting.
Or raise the cutting current a bit if possible.
