INSTRUCTION MANUAL
WARNING:
BEFORE USING THE MACHINE READ THE
INSTRUCTION MANUAL CAREFULLY!

1. SAFETY RULES

ELECTRIC SHOCK MAY KILL
- Electric installation of plasma cutting unit must be
carried out by "SKILLED" personnel in accordance with
ACCIDENT PREVENTION LAWS and RULES.
- Make sure that power supply cable is properly
connected to "EARTH PLATE".
- For power supplies at the higher voltage the welding
machine should be connected only and exclusively to
a power supply system with neutral to ground.
- Avoid any "DIRECT CONT ACT" with NON-insulated
parts of the "CUTTING CIRCUIT". (1)
- Always wear protection clothing. Ex.:insulating gloves
and shoes.
- Keep protection wear clean and do not damage them.
- DO NOT use cables and torch, if the insulation is worn
out or if electric connections are loosened.
- DO NOT use the unit in damp rooms or in the rain.
- Switch off the machine during routine maintenance of
the torch, ex.: replacement of electrode and nozzle.
- Disconnect the machine from the outlet during
installation and operations of inspections and
maintenance.
NOTE (1)
The electric circuit includes all conductors crossed by
cutting current.
IRRADIATION PRODUCED BY PLASMA
ARC MAY DAMAGE
SKIN BURNS.
- Always protect the eyes with adiactinic glasses for iron
soldering set on masks or on graduation helmets: DIN
4-10, depending on the cutting mode (close or distant
mode), and on the intensity of current.
- Wear protective clothing without exposing the skin to
UV rays produced by the arc.
- Make sure that everybody standing in proximity is
protected by the harmful effects of the arc.
SMOKE AND GAS MAY BE
DANGEROUS TO YOUR HEALTH.
- Ensure a proper change of air as well as the existence
of smoke suction devices in the area of the cutting arc.
Ex.: suction benches or at water level.
- Use individual respirators if ventilation is not enough to
intercept all smokes and gases.
- Do not cut material cleaned with chlorinated solvents or
near said solvents: vapors from the action of arc UV
rays may produce toxic gases.
- Avoid cutting on painted, galvanic coated surfaces or
parts dirty with oil or grease; clean the part thoroughly
THE
EYES AND CAUSE
before cutting it.
NOISE MAY DAMAGE HEARING.
- The level of noise produced by the cutting arc may
exceed 85 dB (A).
- Check the level of INDIVIDUAL DAILY EXPOSURE to
the noise.
- Use proper means of individual protection in case the
limit is exceeded.
FIRE AND EXPLOSIONS MAY BE
IGNITED BY SPARKS AND HOT SLAGS.
- Do not cut on containers and pipes containing
inflammable products or liquid and gaseous fuels.
- Remove all inflammable material from the cutting area,
wastes included, ( rags, cartons, etc.) within a range of
10 meters.
- Make sure there are proper fire proof means in the
cutting area.

2.GENERAL INFORMATION

PLASMA ARC AND BASIC PRINCIPLES FOR
THE PERFORMANCE OF PLASMA CUTTING.
- Plasma is a gas which is heated at a very high
temperature and ionized so as to become an electric
conductor.
- This cutting procedure uses plasma to transfer the
electric arc to the metal part which is melted by the heat
and then separated.
- The torch requires compressed air coming from one
feed source both for plasma and for protection and
cooling gas.
- The cycle start is determined by the movement of the
electrode inside the nozzle which strikes a pilot arc
between the electrode (polarity -) and the torch nozzle
(polarity +).
- By bringing the torch near the part to be cut, which is
connected to the + polarity of the current source, the
pilot arc is then moved away thus creating a plasma arc
between the electrode (-) and the piece itself (cutting
arc).
- The pilot arc is switched off as soon as the plasma arc
is established between the electrode and the piece.
