Torch Down Time: torch lifter has no location switch (zero point switch), location feedback set 0, torch down
time end, torch height is arc strike height
Note: when check location feedback, torch down time invalid
Location Up Time: when check location feedback valid, check location switch signal input, close torch down
output, open torch up output, keep location feedback and close, torch height is location height (arc strike
height)
Note: when don’t check location feedback, location up time invalid
Arc Strike Time: time of arc transfer
Pierce Time: torch up to pierce position, start to pierce
Move Pierce Time: after torch starts pierce, before torch down to cutting height, XY start to move, this period
of time to avoid steel slag
Auto THC Delay: after pierce, open the time
Note: set the time, help THC to avoid unsteady arc voltage time and reduce torch shake
Close THC Speed Down Scale: during cutting, speed change is in the range, close auto height adjustment,
reduce arc voltage auto THC wrong action caused by speed change, set 99, cutting speed is 99% of set speed,
don’t close THC auto output caused by speed change
Arc Break Distance: set a position before the end point, close arc strike output in advance, finish left cutting
by left temperature, to avoid overburn.
Note: close THC when break arc
Arc Break Time: check arc strike success feedback valid, set time, so that torch continues to move after arc
break
Note: don’t check arc strike success feedback, time of arc break invalid
Location Feedback: torch lifter has location switch (zero point switch), can set 1, choose check location
feedback, or set 0
Note: set 1, torch location, keep torch down output, till check location switch signal input close
Arc Strike Feedback: open arc strike output, whether check arc strike success feedback signal input, plasma
power or arc voltage auto THC has the signal output, can connect to controller input, set 1
Plasma cutting procedure (no location check and arc strike success check)
