I have a batch of parts to cut on a sodick WEDM with mk21 control using .25mm wire. The parts are 200mm tall and are about 25X16mm. It cut really good for the first 25mm at a speed of .45mm/min. After breaking the wire 3 times I turned down the settings and now get 5-20mins of cutting before the wire breaks. I have noticed that it will move a bit, then the voltage goes down, it stops moving, then the voltage goes back up and it starts moving again. I really need to get this to cut reliably so i can leave it overnight, and get my parts done by the deadline. Any ideas? Should I be using a thicker wire for taller parts? Thanks in advance.
