Trying to get an EDNC-32 running I picked up at an auction earlier this year. Has MGC control. First thing I found is a stuck solenoid that kept the electrode from clamping. I swapped it with the changer arm solenoid so it clamps the electrode. My issue now is when in manual, touch is not working at all. This is a very nice machine, had an upgraded lcd screen added at some point. I’m hoping I can get this think operational.
