Attached is a torch voltage component that will read your torch voltage to use as a setpoint when a signal (eg a delay based on ArcOK)
Before using this, you may like to look at your arc voltage wusing halscope to select a delay time. Here are some of my plots using 2mm steel and 8mm steel.
In both cases, it seemed that 1.5 seconds was a good time frame (eg at the white lines) so I just hardcoded a delay on ArcOk.
To use, its something like this (Example is based on the external offsets branch
