a) Digital ammeter: Displaying cutting current
b) Cutting current adjusting knob: Adjusting cutting current
c) Power indicator lamp: Indicating if the cutter is conducted.
d) Air pressure indicator lamp
：
It is ON when the pressure of compressed air exceeds
0.2Mpa. It is OFF when the pressure is less than 0.15Mpa.
e) Cutting indicator lamp: Indicating if cutting proceeds.
f) Overload indicator lamp: It is ON when the cutter is over loaded(generally because
cooling fan is damaged.)
g) Supply abnormality indicator lamp: It is ON when power source misses phase or it is
less than 310VAC.
h) Gas control selection switch: When it turns on TEST, gas valve opens to test gas flux.
When it turns on Cutting and cutting starts, the gas valve opens automatically.
i)
Operation mode selection switch: When it turns on Non Self-lock, the torch switch
should be pressed at the process of cutting. When it turns on Self-lock, press the
torch switch and loosen it, the cutting can proceed.
j)
Cutting ground wire outlet: To connect cutting ground wire
k) Torch control outlet: To connect torch control signal line
l)
Torch arc striking terminal: To connect torch arc striking wire
m) Output connector of gas and power: The current output connector is also air outlet
which is used for connecting air cooling cable outlet of torch.
n).. Spare wire hole for the are voltage output: the arc voltage output wire is not
connected when the machine finished, when needed, please open the head cover of
the cutter, using a two cored wire to join with the terminal of the LGK7-AP5, which
has two output signal, one is the 1:1 output and the other is 1:20 output, please
connect the wire according to the requirements, and pay attention to the negative and
positive electrode.
o) . Control signal connector: To control automatic cutting equipment
p). Power source switch
：
Control the ON/OFF of 3-phase power supply of cutter.
；
q). Air voltage regulation filter
：
For adjusting usage pressure of compressed air and
filtrating water from air.
r). Hydraulic pressure indicate lights: connect the cooling water supply, when current
>0.45L/min, the light will be on.]
s). The water/air torch choose function: the air torch is only suitable for the air torch
setting position, the same as the water torch.
t). Water/electricity output joint: the current output joint is also the water output joint,, it
is for join with the water cooling cable.
u). The water recycle joint of the torch: It is use for join with the water recycle pipe.
v). Water recycle joint: it is use for join with the water tank recycle pipe.
w). Water input joint: it is use for join with the water tank output pipe.
