3 Operating instructions
3.1 Operation panel interface
1
Current display meter
，
Display preset current and actual current during operation
。
The maximum output current is
55A when the 240V voltage is input, and 35A when the 120V voltage is input.
2
Power light
When this light is on, it means that the power supply is normal.This machine can accept 120V or 240V power
supply.
3
Over current or over heat protection light
When the cutting load is overloaded and the output current of the machine is too large, the internal temperature of
the machine is too high, and the machine fault light will be on. This is normal. The machine can recover after the
heat dissipation becomes normal. Please restart the power supply; When damaged, the fault light will be on, in
this case, the machine is abnormal and needs maintenance, please contact the supplier.
4
Current adjust knob
5
Recommended selection range of air pressure: when 120V is input, it is recommended to adjust the input air
pressure at 30-50PSI; When 240V is input, it is recommended to adjust the input air pressure at 30-70PSI.
3.2 Cutting Operation instruction
On display
After open the power supply,the power light is light,current meter display the preset current.
Preparation
Input cable connection
Every machine has been disposed a power cable which must be connected to coordinated voltage class in
compliance according to input voltage of cutting machine .If cutting machine whose power voltage is 230V is
connected wrong to AC 400V, that will cause components of inter-machine are burned up.
Make sure power cable is connected to power switch reliably and prevent from oxidizing. Make sure power voltage is
inside the waved range.
Connect Air compressor
Make sure tube of pressed air is connected to copper connector by high-pressure rubber tube firmly.
Connect one end of the trachea to the gas in of the machine and the other end to the air compressor.（Refer to 2.2）
