Hurco Agemaspark 580 sinker Settings?

[mossy123]

Hello,

Have had the sinker as per title for several years, its now alive, serviced, filters, Dielectric and tooled.
Need training but before i book this I feel the need to have a little knowledge so what I learn sinks in!
As a test I want to burn a 10mm AF hex 10mm deep in a 9.5mm predrilled hole in 316 stst using HDHC copper electrode.
Any advice and benchmark settings from you guys would be much appreciated.
Have had ago to find a well worn electrode

The hole is blind, job submerged, through flushing on electrode and additional loc line mag-stand flush nozzle to promote partical movement.

Many thanks for your time,
Chris.
