value of piercing delay time will increase. If it turn anticlockwise, the value of
piercing delay time will decrease. When the spin button is turned, the yellow nixie
tube display“Dly”, the red nixie tube display piercing delay time, the unit is second.
When THC use the piercing delay time which user set, it can send arc OK signal
to CNC after piercing delay is finishing and arc voltage by sampling is effective.
Some CNC have piercing delay time, but this delay is calculated when CNC receive
arc OK signal. The authentic piercing delay time is the sum of piercing delay time of
THC and piercing delay time of CNC. If user do not want to use the piercing delay
time of THC, user can set it as zero.
The spin button named
“
IHS Height”
：
When menu operation do not use, turning
the button can change height of IHS. If it turn clockwise, the height of IHS will
increase. If it turn anticlockwise, the height of IHS will decrease. When the spin
button is turned, the green nixie tube display“IHS”, the red nixie tube display the
height of IHS. The height of IHS set by delay, the unit is second.
When menu operation do not use, two nixie tube is display arc voltage setting
value. If user turn the spin button named
“
Piercing Delay
”
or the spin button named
“
IHS Height
”
, it will display corresponding character. If the spin button is not turned
for a long time, the nixie tube will display arc voltage setting value.
3. Working condition indicator
：
The panel have 8 LED light
：
¾
UP indicator
：
This LED light is turned on when torch lift up.
¾
AUTO THC indicator
：
This LED light will be truned on when the THC is
working in auto height controlling processing. If it satisfy four conditions
below, the indicator will turn on
：
1 ） The indicator named
“
AUTO
”
is turned on.
2 ） CNC Auto height control enables.
3 ） THC have sampled valid arc voltage.
4
）
The sampling arc voltage do not exceed the value added
between arc setting voltage and arc protecting voltage(in general, the value is 30V and
can been changed).
¾
TRANS indicator
：
The indicator is lighted, it means system have detected the
effective arc voltage value and piercing have competed. (it is piercing delay
time of THC over, it is not contain the piercing delay time of CNC)
¾
ARC ON indicator
：
Turn on when THC send arc start signal out. If IHS
completed, this indicator is lighted when THC send arc start signal. During
arc start test, the indicator is lighted.
¾
DOWN indicator
：
Turn on when torch lift down.
¾
COLLISION indicator
：
Turn on when torch touch workpiece or proximity
switch effective.
