Operation
3. Attach air regulator as show in picture Air Regulator Installation only for O241.
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. 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.
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.
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.
2.8 Setup For STICK (MMA) Welding O251
For Alkaline Electrode, connect the electrode holder to the positive welding termimal

Electrode, please connect the electrode holder to the negative welding termimal and
connect the work lead to the positve welding terminal.If in doubt consult the electrode
manufacturer. Welding current flows from the Power Source via heavy duty bayonet type
terminals. It is essential, however, that the male plug is inserted and turned securely to
achieve a sound electrical connection. Select STICK mode with the process selection
control.
