Trying to get the 8 pod system 3r ATC working. (Its the old pin style). I have most of it troubleshot, but the problem now is the airline that runs to the chuck does not release the electrode. Infact it was disconnected and I have NO idea how to connect it. There is also a small airline that was cut at the backside of the changer system. Does anyone know where I can start with this? I have too many hours into fixing it to quit at this point lol
