Notes:
* Contact closes after arc transfer and time delay
** To enable a remote ON/OFF switch, the jumper on TB4 must be moved from
terminals 1&2 to terminals 2&3 - see figure.
*** A contact closure will activate pierce complete and keeps shield in preflow
mode. Open the contacts for shield cutflow mode.
Note on the µP PCB that resistor R150 and capacitor C78 are connected in
series across the contacts. In some cases, one lead of R150 must be cut from
the control PC board, as the R-C circuit may provide enough current flow to
maintain machine motion input to the cutting machine.
