NOTES:
1.
When the torch switch is pushed during postflow period, the postflow and preflow times are canceled, and the HF
is energized immediately.
2.
When the red fault light comes on, cutting operation should be stopped. The postflow time starts from the moment
the torch switch is released.
3.
FAULT light is on during second "turn-off" trigger only. This does not affect performance in any way.
