Hello, I am building a mini Wire EDM at a small scale and I haven't had the chance (yet) to study a real wire edm machine. All my knowledge is based on documents, youtube videos and so on. What I would like to know is when the AUTO threading is enabled on a machine, the wire travels through a water jet aimed at the lower guide (correct me if I am wrong) and after that I would like to know how the wire travel up to the cutter. Is the wire inserted through a small diameter tube and after it travels a certain distance , roller driven by small motors are taking the wire to the cutter?
