| Ive been asked by a couple of people to post up a schematic of exactly how my voltage divider works, ive attached it underneath, i have also included a relay activated by the arc ok signal to connect the system to the plasma after the pierce has taken place. Matt  |

I'm curious, haven't had a chance to look into "Arc OK". What conditions close this contact on the cutter? Also, what conditions open the contact? karl |

| Hypertherm calls it "arc transfer" or "machine motion". When current is sensed through the work lead.....a relay closes in the plasma system.....this indicates that the plasma aec has transferred to the plate. If current is lost through the work lead....the relay contacts open. Jim Colt |
