）
1.
Digital ammeter: Displaying pre-set cutting current before cutting, displaying cutting
current when cutting
2.
Cutting current adjusting knob: Adjusting cutting current
3.
Power indicator lamp: Indicating if the cutter is energized.
4.
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.
5.
Cutting indicator lamp: When the lamp ON means the cutting machine has started.
6.
Overload indicator lamp: It is ON when the cutter is over loaded (generally it is on when
cooling fan is damaged.)
7.
Input fault indicator lamp: It is ON when power source misses phase or it is less than
330VAC.
8.
Gas control selection switch: When it switches to Check air, gas valve opens to test gas
flux. When it switches to Cutting, the gas valve opens during cutting automatically.
9.
Torch operation mode selection switch: When it turns on 2-Step, the torch switch should be
pressed at the process of cutting, and the cutting comes to stop after loosening the switch.
When it turns on 4-Step, press the torch switch and loosen it, the cutting starts to work, and
comes to stop after pressing the switch again.
10.
Cutting ground wire outlet: To connect cutting ground wire
11.
Torch Pilot terminal: To connect torch pilot wire.
12.
Torch control outlet: To connect torch control signal wire.
13.
Air & Power output terminal: the current output terminal is also the compressed air output
terminal. It is gas pipe connector to connect water-cooled torch when the water-cooled
torch is used, and it is connector to connect torch gas-cooled cable when air-cooled torch is
used.
14.
Spare wire hole for arc voltage output: the arc voltage output wire is not connected when
the machine is finished. If it is needed, please open the cutter top cover, and use two-core
wire to connect the wire terminal on printed board LGK7-AP5, which has two kinds of
output signal, one is the 1:1 output and the other is 1:20 output, please
