Greetings,
Does anyone have suggestions for cutting pure tungsten (99.95%) with copper electrodes on a 1986 Hansvedt 201? I've been able to do it with negative polarity on the electrode, but it's just unbelievably slow and the electrode wear is atrocious. The dielectric is new Ionoplus. I started with the recommended settings for tungsten carbide, and then did a lot of experimenting. I'm trying to cut some holes using tubular electrodes and flushing through the tube. Anyone ever done this?
It seems most of the time people end up cutting heavy tungsten alloys, copper tungsten, radiation shielding tungsten alloys, etc., which have other elements in it that make it much more manageable. This pure stuff is unbelievably tough (can't cut it with carbide, for example).
Thanks!
