• Do not use leaking or damaged bottles.
• Do not use not well fixed bottles.
• Do not carry bottles whose content is not clearly identified.
• Never lubricate bottle valves with oil or grease.
• Do not put electrically in contact bottle with plasma arc.
• Do not expose bottles to excessive heat, sparks, hot metal
or flames.
• Do not tamper bottle valves.
• Do not try to losen all tight valves by means of hammers, keys
or something else.
B) PRESSURE REGULATORS
• Keep pressure regulators in good conditions. Damaged
regulators may give rise to damage or accidents; they should
only be repaired by skilled personnel.
• Do not use regulators for gases other than those they are
manufactured for.
• Never use a leaking or damaged regulator.
• Never lubricate regulators with oil or grease.
C) AIR HOSES
• Replace air hoses if damaged.
• Keep hoses unwound so as to avoid from bending.
• Keep the exceeding hose wound and keep it out of the
working area so as to avoid any damage.
NOISE
These power sources alone do not produce noise
levels exceeding 80 dB. The cutting procedure,
however, may produce noise levels in excess of 80 dB in which
case the operator must take the necessary safety precautions
as prescribed by the national safety regulations.
PACEMAKER
Magnetic fields created by the high currents in the cutting circuit
can affect pacemaker operation. Persons wearing electronic
life support equipment (pacemakers) should consult their doctor
before going near any arc welding, gouging, cutting, or spot
welding equipment in operation.
SAFETY DEVICES
This unit is provided with the following safety devices:
Thermic: located on the power transformer windings to avoid
overloads and signalled by indicator light G on (see picture 1).
Pneumatic: located on the torch feed line to avoid insufficient
air pressure and signalled by indicator light L (see picture 1).
Electric: 1) located on torch body to avoid dangerous
voltages while replacing nozzle, diffuser, electrode or nozzle
holder.
2) To stop the unit when the electrode is so worn that it is
required to be replaced. This second function is signalled by
indicator light (N) (picture 1).
• Do not remove or short-circuit the unit safety devices.
• Only use original spares.
• Always replace any damaged part of the unit or torch
with original material.
• Do not use any torches other than the original one.
• Do not let the unit work without covers. This would
be dangerous for operator and for those who are surroun-
ding the work area and would prevent the unit from
cooling efficiently.

ASSEMBLY AND ARRANGEMENT
Unpack the unit, fit wheels, stand and handle following the
instructions of picture 2. Place the unit in properly ventilated if
possible undusty room making sure that the air inlet and outlet
from cooling slots are not obstructed.
Fit torch on the unit Fig. 1 by tightening the adapter ring nut (Q)
to the fixed fitting (P) thus avoiding air leaks damaging torch
working. Pay particular attention not to dent the power pin and
not to bend the adapter pins (Q); a dented pin cannot be
disconnected, once fit, from the fixed fitting (P); a bent pin
prevents the adapter (Q) from being correctly mounted on the
fixed fitting (P) and the unit from working.
