1 SAFETY INSTRUCTIONS

ELECTRIC SHOCK CAN KILL

- Disconnect the power supply before working on the plasma
machine.

- Do not work with deteriorated cable sheaths.

- Do not touch bare electrical parts.

- Ensure that all the panels covering the plasma machine are firmly
secured in place when the machine is connected to the mains
supply.

- Insulate yourself from the work bench and from the floor (ground):
use insulating footwear and gloves.

- Keep gloves, footwear, clothes, the work area and this equipment
clean and dry.

PRESSURISED CONTAINERS CAN EXPLODE IF WELDED.

When working with a plasma machine:

- do not cut pressurised container.

- do not cut in environments containing explosive powders or
vapours.

THE RADIATIONS GENERATED BY THE WELDING ARC CAN
DAMAGE THE EYES AND CAUSE BURNING OF THE SKIN.

- Provide suitable protection for the eyes and body.

- It is indispensable for contact lens wearers to protect
themselves with suitable lenses and masks.

NOISE CAN DAMAGE YOUR HEARING.

- Protect yourself suitably to avoid hearing damage.

FUMES AND GASES CAN DAMAGE YOUR HEALTH.

- Keep your head out of the reach of fumes.

- Provide suitable ventilation of the work area.

- If the ventilation is not sufficient, use an exhaust system that sucks from the bottom.

HEAT, SPLASHES OF MOLTEN METAL AND SPARKS CAN CAUSE FIRES.

- Do not cut near inflammable materials.

- Avoid having any type of fuel with you such as cigarette lighters or matches.

- The cutting sparks can cause burns. Keep the tip of the electrode far from your body and from other
persons.

PREVENTION OF ELECTRIC SHOCKS

Take the following precautions when working with a plasma machine:

- keep yourself and your clothes clean.

- do not be in contact with damp or wet parts when working with the plasma machine.

- maintain suitable insulation against electric shock. If the operator has to work in a damp environment, he
must take extreme care and wear insulating footwear and gloves.

- check the machine power cable frequently: it must be free from damage to the insulation. BARE CABLES
ARE DANGEROUS. Do not use the machine if the power cable is damaged; it must be replaced
immediately.

- if it is necessary to open the machine, first disconnect the power supply. Wait 5 minutes to allow the
capacitors to discharge. Failure to take this precaution may expose the operator to dangerous risks of
electric shock.

- never work with the plasma machine if the protective cover is not in place.

- ensure that the earth connection of the power supply cable is perfectly efficient.
This machine has been designed for use in a professional and industrial environment. For other types of
application contact the manufacturer. If electromagnetic disturbances are found it is the responsibility of
the machine user to solve the problem with the technical assistance of the manufacturer.

It is forbidden for people with PACEMAKERS to use or come near the machine.

PREVENTION OF BURNS

To protect your eyes and skin from burns and ultraviolet rays:

- wear dark glasses. Wear suitable clothing, gloves and footwear.

- use masks with closed sides, having lenses and protective glass according to standards (degree of
protection DIN 10).

- warn people in the vicinity not to look directly at the arc.

PREVENTION OF FIRE

Plasma cutting produces splashes of molten metal.
Take the following precautions to prevent fire:

- ensure that there is a fire extinguisher in the welding area.

- remove all inflammable material from the immediate vicinity of the welding area.

- cool the cut material or let it cool before touching it or putting it in contact with combustible material

- never use the machine for cutting containers of potentially inflammable material. These containers must be
completely cleaned before they are cut.

- ventilate the potentially inflammable area before using the machine.

- do not use the machine in atmospheres containing high concentrations of powders, inflammable gases or
combustible vapours.

3 INSTALLATION

WARNING: This Class A equipment is not intended for use in residential locations where the electrical
power is provided by the public low-voltage supply system. There may be potential difficulties in ensuring
electromagnetic compatibility in those locations, due to conducted as well as radiated disturbances. This
equipment is complying with IEC 61000-3-12 and It can be connect to a public and private low voltage
system. The good operation of the machine is ensured by correct installation; you must therefore proceed as
follows:

- Position the machine in such a way that there is no obstacle to the air circulation ensured by the internal fan
since the internal components require suitable cooling.

- Ensure that the fan does not send deposits or dust into the machine.

- Avoid impacts, rubbing, and – absolutely no exposure to dripping water, excessive heat sources, or any
abnormal situations.

CONNECTION

- Before making the electrical connections between the Inverter and the line switch, ensure that the switch is
turned off.

- The distribution panel must comply with the regulations in force in the country of use.

- The mains system must be of the industrial type.

- When using long extension cables, the core diameter section is increased as required for optimum performance.

- The power input supply socket must have a suitable switch provided with slow burning' type fuse(s).

- In the event of damage to the power cable, replacement or repair must be performed by a qualified person at an
approved service centre.

EARTHING

- To ensure user protection the Inverter must by law
be correctly connected to the earth system
(INTERNATIONAL SAFETY REGULATIONS).

- It is necessary to provide good earthing by means of
the yellow-green wire in the power cable, in order to
avoid discharges due to accidental contacts with
earthed objects.

- The chassis (which is conductive) is electrically
connected with the earth wire; if the equipment is not
suitably connected to earth it may cause electric
shocks which are dangerous to the user and those
nearby.

PNEUMATIC CIRCUIT CONNECTION:

The machine uses compressed air for plasma cutting. Any cylinder of compressed air may therefore be
used, or air from a compressor. The air must be free from polluting particles, such as oil or other
contaminating agents. A pressure regulator is provided to ensure the correct air flow rate on the torch.

KEY:

1– Air filter
2– Reducer (pressure regulator)
3– Pressure gauge
4– Pressure switch
5– Solenoid valves

A pressure between 5 bar and 5.5 bar must be applied to the air filter located on the rear panel of the
machine (100l/min). The pressure must not exceed 6 bar. The pressure regulator 1 is set by the
manufacturer at 4.8 bar. Check the pressure by pressing the Air Test button on the front panel and check
that the pressure gauge gives a reading of 4.8 bar. If necessary to the correct pressure by turning the knob
on the pressure regulator.

A pressure switch (4) in the machine will stop operation if the pressure at output of the reducer (2) is below 3
bar, which is minimum to guarantee operation.
