All of the electrodes seem to be touching the work when the pulse is fired, do all of them scratch start the arc?

Sunstone says the default ignition retracts the electrode at the same time the arc fires. There is an option to have the arc fire after the electrode has retracted. The final setting is "pre heat" which sounds like a combination of the two with a smaller discharge when retraction starts, then the main discharge after retraction occurs.

Initiation can be automatic from workpiece contact or a manual foot pedal

No idea how critical any of this is.
