Re: [CAD_CAM_EDM_DRO] Wire edm specs

Steve,
some small input to the wire EDM p/s.
They are often 100 to 200 AMPS at 100 to 150 VDC !
But, the duty cycle is small so the Power, Watt/secs is low enuf to allow a
10KVA trafo to cruise.
On & Off times dont have the range as in Sinking EDM. On times from maybe
0.5 to 10uS and Off from 10 to 40.
These are not exact at all ( esp not for your edm whoever you may be or from
who you may have bought it...)
Anyways the wire edm p/s is hi power teeny burst o plasma generator.
designed to punch thru a pretty static
clean constant sheath of water controlled in velocity ( fast = didnt stick
around long enuf to get dirty and conductive)
and of a specific conductance ( msrd in Mhos or 1/ohm or resistivity, each
manufacturer tried to make thiers
different tho principle is same).
The duty cycle is aggravated by many pulses being lost, so the average
curent is likely never higher than 10 amps
(big bait for big fish?)

The data you found for GapVolts is meant to be a guide for user during
ruf/pre-fin&finish passes. But the data is
bound to the electronics used to detect and display. The value on a meter
varies with duty cycle unless some
sample and hold is used, for instance.

Newer equipment (ala AC supplies are different yet, but this applies closer
to home brew )

BTW: the 'new' GPL'd CAD system gCAD3D is really nice & definitely will
become a wire EDM tool.
only about 650K if you have the GL libs already.
