Yes. I guess I need to move it over. While the basic voltage
sensing circuit of the posted schematic remains the same we have made
several additions and modifications to the version that will be
available from Bob Campbell. We have added a universal current
sensor for the plasma side that works with any machine for the "Arc
Good" signal. Jim at Sound Logic is doing the design and has added
the buffers and isolation for the second parallel port that is
usually need for the added inputs.
