Operation
8. Tighten the back cap.
9. Turn the switch to the "ON" position. The power L.E.D. light should illuminate.
10. Set the welding process to HF TIG.
11. Set the Weld Current Control Knob to the desired amperage.
12. You are now ready to begin HF TIG Welding.
3.4 Setup for cutting
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.
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.

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.
9. Make sure that the torch has been assembled with the correct components and that the
cutting tip is suitable for the cutting current.
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.
12. Contact the copper tip of the torch to the work piece, press the button of the forch until
the arc-starting and raise the cutting torch about 1mm above the work piece, and perform
the cutting operation.
13. 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.
CAUTION
Do not point the torch jet at foreign bodies.

CAUTION
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.
