6. Work Indicator
Turn on the switch of the cuttign gun,generate the voltage, the lamp on.
7. Grid Cut Indicator
Press and release button from 8 to change the selected cutting functions mode, light on ,
the function is selected.
8. Normal Cut Indicator
Press and release button from 8 to change the selected cutting functions mode, light on ,
the function is selected.
9. Cut function Select Button
Press and release this button to change the selected cutting functions mode.
10. Positive Control
The positive control is used to plus current.
11. Negative Control
The negative control is used to minus current.
12. Positive Welding Output Terminal
The positive cutting terminal is used to connect the cutting output of the power source
to the appropriate welding accessory such as earth clamp. It is essential, however, that
the male plug is inserted and turned securely to achieve a sound electrical connection.
13. Plasma Torch Connector
Plasma torch insert in to connect with the machine. It's necessary to be sure that the
plug is correctly and tightly connected to maintain the electricity and gas supply.

2.5 Installation Instructions
In order for the unit to function correctly, it must be installed properly. Follow the procedure
given below for correct installation:
1. Read the safety rules given in this manual carefully.
2. Check on receiving the unit that there are no defective parts or parts damaged during
transportation.
3. Attach air regulator as show in picture Air Regulator Installation only for C71.
4. Set your unit up in an area which is adequately ventilated and make sure that the air
vents are not obstructed.
5. Connect the power supply cable to a socket located as near as possible to the work area,
so that the unit can be switched off quickly in case of emergency.
6. Your machine has a 16 amp plug fitted, before use check that the green/yellow earth is
connected to the earth pin socket of fitted plug.
7. Make sure that the mains supply switch and any fuses have a value which ± 15% the
maximum current absorbed by the unit. All fuses should be the slow-blow type.
8. Any extensions of power supply cable should have the same cross-section as the power
supply cable. The extension leads, however, should only be used when absolutely
necessary. It is important to note that any extension of mains cables or torch cables will
possibly affect the cutting performance of this cutting equipment, due to the fact that the
resistance of the cable will reduce voltage input, which is determined by the length of the
cable. The supplied length of main cables and torch cables is recommended.
9. Fasten the earth clamp to the piece to be cut, If the surface of the piece to be cut is
painted, rusty or covered with insulating material, clean the surface so that
satisfactory contact between the piece and the earth clamp can be obtained.
10. Make sure that the torch has been assembled with the correct components and that the
cutting tip is suitable for the cutting current.
11. Connect air to regulator and adjust regulator to deliver 5-6 bar 90ltr/min
12. Switch the unit on using the main switch located on the back side.
13. press the cutting torch to achieve a pilot from the copper tip, when this pilot is up to the
work piece , cutting operation begins.
14. Once cutting is over, release the torch button to put out the arc. A period of post-flow
time 45 to 75 seconds (required for torch cooling) will follow. Do not disconnect air
until this cooling period has been completed. Failure to do this will result in torch head
damage.
