2.

Pull out the air pressure reglator knob, (located on the front panel (King 50 & 70), or
at the back of the unit (King 35), and turn it fully clockwise before connecting the
air hose to the compressed air supply. This ensures  the regulator is set to its lowest
pressure. Make sure that the supply pressure is at least 6 bar (from 6 to 8 is ideal).

Turn the air supply to the unit ‘on’, and set a pressure of 5 to 5.5 bar by screwing the
regulator knob anticlockwise, whilst observing the pressure on the gauge. When the
pressure is set, lock the knob in position, by pushing it ‘in’.

3.

Fasten the earth clamp to the workpiece. If a metal bench is being used, make sure
it has also been connected to earth by means of a cable with an adequate cross-
section.  If the surface of the piece to be cut is painted, rusty of covered with insulating
material, clean the surface so that satisfactory contact between the workpiece
and the earth clamp can be obtained.

4. Make sure that the torch has been assembled with the correct components and

that the  hole in the tip of the torch complies with the values given in the table below,
according to the cutting current. Simply unscrew the nozzle, and replace with one of
the required size.

5. Switch the unit ON using the main switch (see Figs 2 & 3), Select the appropriate

current in the case of King50 and King70. A hissing of air will be apparent for a short
period, as the air system is charged and the air filter drain valves close

6. Check to ensure the amber lights for air supply, and torch safety, (i.e. Thermal

Overload), situated on the front panel, are off. The green light should be ‘on’, indicating
that the unit is supplied with power.

7.

Press the torch button and check whether the pressure indicated by the pressure
gauge corresponds to the pressure required. At the same time, the Pilot Arc will light.

Because these models are fitted with a Pilot Arc, cutting can commence even on
metal which is painted or coated. However, do be aware that fumes may be given
off by burning paint or coated surfaces.

8.

The pilot arc will go out after 2-3 seconds. If in the meantime cutting has not started,
the torch button should be pressed again so that pilot arc will relight.

CAUTION:

Avoid unnecessary lighting of the pilot arc, to prevent excessive consumption   of

the electrode and nozzle.
