Hello. I am using Powermax65 Sync by Hypertherm. The CPC cable has 4 spade connectors. 2 are for the torch on and off that connect to the back of the ArcDroid. The other 2 spades are for “Arc Transfer”. Are these to also be connected to the Aux connections on the ArcDroid, or are they simply not needed? Excuse my ignorance, I am new to CNC plasma cutting.  
I read a few other threads on here, and feel I should mention I am using a Machine torch.

They are not needed unless you want to try the torch height control.

IN fact @BobD they are not need at all even if you do use the THC function

ArcTransfer is a signal from the plasma to a CNC system saying “we’re lit you can go” we do not use that signal at all regardless of THC or not

What do you use instead, to notify the arc droid “we’re lit you can go”?

Just a Pierce Delay setting to give the arc time to stabilize before the ArcDroid starts moving.
