Trigger is enabled as soon as the machine is energised

the trigger output for plasma is on as soon as i apply power to my machine even on the pcb the led light in on for the trigger output. would it be fair to say that the output is shorted internally?

As soon as the Droid is turned on or the plasma cutter?

as soon as tghe droid is turned on

Does it do this with the stylus plugged in?

yep
and with the plasma cancel button selected on display

Sounds like the relay has welded its contacts together. I would contact Andrew at Arcdroid for assistance.

yeah but the circuit opens when you deenergise the droid

I dunno. I take it you had this working ok until it wasn’t? Contact Andrew.
