Portable Plasma Torch Height Controller Manual (F1620)
start.
【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 have been pressed, and it can stop start arc(arc relay
is opened) when button have 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 have 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 suit to adjust slightly torch height when
torch is working.
The spin button named“Piercing Delay” ：When menu operation do not use,
turning the button can change the value of piercing delay time. If it turn clockwise, the
