What exactly are you doing when it shocks? Touching the case, the electrode, the workpiece or the connections? Or two of them at the same time? Are you wearing gloves? Have you checked the protecting earth wire (ohm meter between the case and the mains connector earth)? Have you tried to use the machine in different buildings? (Wiring problems of the building)
