I have a hypertherm 45 sync and the Machine Interface Receptacle and the Machine torch.
After installing all the misc boards, cables and parts I was unable to get the torch to fire when I ran the arcdroid.
It turns out that the most recent instructions reference a wire that may not exist on all kits.
On mine the 4-wire connection does not have a orange wire as referenced in the manual. To add to the confusion the plug will fit both ways so there is no clue to be had there.
On my machine I have to have the red wire at the top, not the missing orange wire, to get things working.
I’m including pictures. Hope this helps someone.
