5.2 Automatic operation
Reach to automatically adjustable requirement:
1. Start arc (ARC) signal effectively.
2. Automatic (AUTO) signal effectively.
3. Appropriate plasma cutting voltage ((set voltage-50) ~ (set voltage + 60)).
Initial positioning: the block after receives the start arc (ARC) block driving
down hoisting mechanism, Zero point (Zero) signal is valid, said cutting device
has met the steel plate, the tones to rise block driven lifting gear, rise time for
"IHS time", "IHS time" to finish the initial alignment is complete.
Start arc output: after the completion of the initial positioning output and arc
signal to the plasma power, such as waiting for a time after acquisition of arc
voltage.
Start arc successful feedback: the arc voltage within a certain amount of time
keeping within the normal range is rev arc (perforated) has been successful,
the block signal success (0-OK) to the numerical control system.
Automatic tracking: in success (0-OK) signal was given and the numerical
control system that start arc can be cut to walk successfully, at this time as
long as the numerical control to the block signal automatic (AUTO) to the block,
the block will enter into the state of automatic tracking.
