CAUTION
Loose welding terminal connections can cause
overheating and result in the male plug being
fused in the bayonet terminal.
3.2 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. Set your unit up in an area which is adequately ventilated and make sure that the air vents
are not obstructed.
4. 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.
5. 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.
6. 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. 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.
7. 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.
10. Connect air to regulator and adjust regulator to deliver 5-6 bar 90ltr/min
11. Switch the unit on using the main switch located on the back side.
9. Make sure that the torch has been assembled with the correct components and that the cutting
tip is suitable for the cutting current.
12. press the cutting torch to achieve a pilot from the copper tip, when this pilot is up to the
work piece , cutting operation begins.
CAUTION
Do not point the torch jet at foreign bodies.

CAUTION
CAUTION
Avoid unnecessary lighting of the pilot arc toprevent excessive consumption of the
electrodeand nozzle.
During cutting the speed of the torch movement should be in accordance with the thickness
of the piece to be cut. Excessive speed causes a return of incandescent towards the torch
which shortens the life of the parts of the torch most subject to wear and tear. The metal
fouling on the nozzle should be removed as soon as possible.
3.Fix the connecting shelf with screw as the regulator position.
4.Get down the plastic screw and fix the regulator on the shelf.
Air regulator installation and operation
1. Firmly tight and seal the copper air hole at IN and OUT terminal by high pressure rubber
tube .
2.Tight and seal the meter with meter face rubber tube.
