NOTE
If a short out interrupts the operation; check the air nozzle and vee block in the
torch head for signs of arcing. If arcing is evident make appropriate repairs. If
no signs of arcing are present, retry starting the gouge procedure by pressing the
“Start” button on the controller or pendant.
13. When the electrode goes off the workpiece or at any time the controller does not
sense current flow, the system’s “NO-CURRENT DETECT” function is activated and
the controller signals the contactor to stop. DC power to the torch head is shut off,
the electrode retracts and the compressed air will shut off as soon as the delay timer
runs out.
NO-CURRENT DETECT FUNCTION
The N6000 System contains a “No-Current Detect” circuit. This circuit monitors Arc Current.
Should the arc stop, this circuit will shut down the gouging sequence.
This circuitry can be set for one of three response levels:
NORMAL - Setting provides 0.2 second shutdown delay.
SPECIAL - Setting provides 0.8 second shutdown delay.
OFF - The N6000 System continues to operate regardless of Arc Current level. System shutdown
is manually controlled.
