I belive this is the HSD spindel that is in question on these cutters.
Taney said it was from italy and this company is from italy and called HSD. I bet they are more knolegable on this 3phase 1 phase 208/240/250 volt amperage song and dance we are trying to figure out. I may contact tehem to and I hop that carvin marvin is reading this and getting his machine wired up. contact these guys if this is the spindel you have, maybe they can helf figure out your voltage and amperage problems. later
