What is the abbreviation of EDM forming machine (electric pulse) processing problem?

Oh my God! Such an old-fashioned spark machine, it must be a hand-operated machine. Didn't the manufacturer provide training when you bought it? I am a manufacturer of spark machines. We no longer produce hand-operated machines like yours. What we now make are three-axis three-linkage CNC mirror spark machines. Every machine in our factory will be assembled and debugged free of charge. Personnel training and one-year free warranty.
