【ARCON TEST】: it is also named as 【ARCON TEST】. During torch do not work and menu
operation do not use, plasma can start arc(arc start relay is closed) when button has been
pressed, and it can stop start arc(arc relay is opened) when button has been loosened. If arc
start button of testing is loosened, torch will lift up an height which named torch accomplishment
height of putting the spear.
【IHS TEST】: it is also named as 【IHS TEST】. IHS button of testing. During torch do not work
and menu operation do not use, if the button is pressed first, THC will start IHS until down is
accomplished. If the button is pressed again during down is working, or 【▲】is pressed, down
will stop work. The light above the button is lighted during IHS test. If IHS test finish, the light will
go out.
2.2 operation panel of explaining
1.Displaying with Nixie tube: Arc voltage value is displayed by two nixie tubes in the
front operation panel. During torch do not work and menu operation do not been used, it can
display arc voltage 、IHS 、pierce delay value and so on. The green nixie tube is used to display
arc voltage setting value; the red nixie tube is used for display actual value of arc voltage. Arc
voltage setting value can be changed by turning the button named【ARC SET】【(ARC SET】)，
and the value displayed with green nixie tube will be changed at the same time. The red nixie
tube display 0 when plasma do not been working. The value displayed with red nixie tube is
actual arc voltage value during plasma is working.
2.Parameter spin button of setting:
There has three spin button of spin encoding in panel.
The spin button named“ARC SET”: When menu operation do not use, arc voltage value
can change by turning this spin button. If it turn clockwise, arc voltage value will increase. If it
turn anticlockwise, arc voltage value will decrease. Arc voltage setting value is displayed in
yellow nixe tube. When we change arc voltage setting value, it should on the basis of workpiece
thickness and torch speed, it also need use parameter which offer by plasma power source.
Torch height depend on Arc voltage value when torch is working.
During torch is working, arc voltage setting value also can change by spin button, and it can
adjust torch height. This operation suitable able to adjust slightly torch height when torch is
working.
