EN-1

Thank you for purchasing our products. When

assembled and used correctly, our welding gene-

rators are reliable and long-lasting and will help

increase the productivity of your business with

minimum maintenance costs.

All these appliances were designed, manufactured

and tested entirely in Italy, in full accordance with

the European Directives of Low Voltage (2006/95/

EC) and EMC (2004/108/EC), by applying norms

EN 60974.1 (safety rules for electric material, Part 1:

source of welding current) and EN 60974-10 (EMC

Electromagnetic Compatibility) and are identified as

Class A products.

Class A appliances were not designed for use in

domestic environments in which power is supplied

through a public low-voltage grid; it is therefore po-

tentially difficult to ensure the electromagnetic com-

patibility of Class A appliances in such environments,

due to radiated and conduced disturbances.

These professional electric appliances must therefore

only be used in industrial environments, connected

to private power distribution cabins.

These generators are therefore not subject to the

European/International EN/IEC regulation 61000-

3-12 which defines the maximum levels of harmonic

distortion induced in the public grid of low-voltage

power distribution.

The installer or the user (if necessary, contact your

power distributor) is responsible for ensuring that

these appliances can be connected to a public low-

voltage grid.

Warning: the manufacturer refuses all re-

sponsibility in the event of unauthorized mo-

difications performed on its products.

FOREWORD

These power generators must only be used for the

cutting procedures described in this manual; they

must never be employed to recharge batteries, for the

thawing of water pipes, for the heating of buildings

by means of added resistances etc.

Compliance to RoHS Directive: We hereby declare

that this range of generators 3Ph described in this

manual is in accordance with RoHS EU Regulations

2011/65/UE of 8 June 2011 regarding the restriction

of the use of certain substances harmful for human

health present in Electric and Electronic Equipment

(EEE).

This symbol, applied to the welding generator

or to its packaging, indicates that, at the end

of its useful life, the product must not be tre-

ated as ordinary waste, but must be collected

separately from other waste and in accordan-

ce with European Directive 2012/19/UE of 4

July 2012 regarding the disposal of waste

electrical and electronic equipment (WEEE).

These must be collected separately and di-

sposed of in an environmentally compatible

way.

As owner of an EEE product (Electrical Electronic

Equipment), you are responsible for contacting your

area dealers for information on authorized collectors.

Applying the above mentioned European Directive

improves the environment and our own health.

Warning: Welding, cutting and similar tech-

niques may be dangerous operations for

the worker and for anyone near the wor-

king area. Please carefully read the SAFE-

TY chapter below in order to reduce risks.

SAFETY

WARNINGS

This manual contains instructions for the proper in-

stallation of the Electric Electronic Equipment (EEE)

you have just purchased.

The owner of an EEE must make sure that this

document is read and understood by welding tech-

nicians and their assistants and by maintenance

technicians.

Warning: Even when the ON/OFF switch of

the EEE is at “O”, voltage from the power grid

is still present within the generator and in the

power cable. Prior to any internal inspection,

make sure the appliance has been discon-

nected from the power source (this means ta-

king a series of steps in order to separate the

appliance from the power source and to keep

it free from voltage).

Electrical electronic appliances may never be used

without their panels and covers, as this may be

dangerous for the workers involved. Using the ap-

pliances without these protections may cause serious

damage to the appliances themselves.

These generators may be supplied by an electricity

generator, which must absolutely be equipped with

a diesel engine with a power higher than the power

required by the generator (see technical data table)

and output voltage of 400Vac +/- 10% - 3Ph –

50/60Hz.

PERSONAL PROTECTION

• Workers and their assistants must protect

themselves by wearing closed, non-flamma-

ble protection coveralls, without pockets or

rolled sleeves or legs. Any residue of oil or

grease must be cleaned from the garments

before wearing them. Only wear CE marked

garments suitable for arc welding and cutting

(Fig. 1):

1. Gloves;

2. Apron or jacket made of crust leather;

3. Gaiters to protect the shoes and the bottoms

of the trousers;

4. Protection shoes with steel toes and rubber soles;

5. Mask (please consult the paragraph on light

radiations);

6. Crust leather sleeves to protect the arms.

• Users must wear fireproof helmet or mask,

designed in such a manner as to offer protec-

tion to the neck and face (including the sides)

against the light of the electric arc (glare from

the visible light and infrared and ultraviolet

radiations). The helmet or the mask must be

equipped with a protector whose degree of

opacity will depend on the welding or cutting

procedure and on the value of the electric arc

current, according to the values contained in

Table 1 (EN 169).

Figure 1

Caution: Make sure all protection gar-

ments are in good conditions and replace

them regularly in order to ensure perfect

personal protection.

LIGHT RADIATIONS

Warning: Never stare at an electric arc wi-

thout suitable eye protection (Fig. 2).

Figure 2

According to the requirements in 2006/25/

EC Directive and EN 12198 Standard, the

equipment is a category 2. It makes com-

pulsory the adoption of Personal Protective

Equipment (PPE) having filter with a pro-

tection degree up to a maximum of 15, as

required by EN169 Standard.

• The colored filter (inactinic filter) must be kept

clean at all times. Should it break or dete-

riorate (Fig. 3), replace it with a new filter,

with the same degree of opacity. The colored

filter must be protected against impact and

welding or cutting projections by means of a

transparent glass positioned on the anterior

part of the mask. This transparent glass must

be replaced whenever visibility is reduced du-

ring welding.

WORKING AREA

Welding or cutting operations must be carried out

in a sufficiently ventilated place, isolated from other

working areas. If this is not possible, anyone near

the person operating the welding machine and

their assistants must be protected by curtains and

Optical Radiation Emission

Category 2

(EN 12198)

EN-3

• Prior to any welding or cutting operation, cle-

ar the working area from all chlorine solvents,

which are normally used to clean or degrea-

se the working material. The fumes of these

solvents, when submitted to the radiations of

an electric arc, even from afar, may, in some

cases, transform into toxic gases. Make sure

all the pieces which are to be welded or cut

are absolutely dry.

Warning: When the welding operator is in

a closed space, the use of chlorine solvents

is absolutely forbidden in the presence of

electric arcs.

• During the grinding, brushing and hamme-

ring operations involving the welded pieces,

always wear protection goggles with transpa-

rent lens to prevent projected chips and any

other foreign particles from hurting your eyes

(Fig. 5).

transparent opaque screens, self-extinguishable and

in accordance with regulation in force (the color of

the screen will depend on the welding process and

on the value of the currents used), anti-UV goggles

and, if necessary, masks with suitable protection

filter (Fig. 4).

Figure 4

Figure 6

Figure 5

Unhealthy or dangerous gases or fumes must be

collected (as they are produced) as close and effi-

ciently as possible to the source of emission, in such

a manner that the concentration of pollutants does

not exceed the permitted limits (Fig. 6). In addition,

all welding operations must be carried out on metal

surfaces devoid of rust and paint, to avoid the

formation of hazardous fumes.

Any symptom of discomfort or pain in the eyes, nose

or throat may be caused by inadequate ventilation;

if this is the case, immediately interrupt work and

ventilate the area.

Do not weld or cut metals or painted metals contai-

ning zinc, lead, cadmium or beryllium, unless the

operator and the persons nearby are using breathing

apparatuses or wearing helmets with oxygen cylinder.

Should welding or cutting operations be carried out

in conditions different from the usual working condi-

tions, with an increased risk of electric shock (reduced

or damp working area), additional precautions must

be taken, such as:

• Using power generators marked “S”;

• Placing the power generator out of the wor-

king area;

• Reinforcing personal protection devices,

ground insulation and insulation between the

piece to be welded and the operator (Fig. 7).

Figure 7

Workers and their assistances must never allow

any parts of their bodies to come into contact with

metallic materials at high temperatures or which are

moving (Fig. 8).

EN-4

Figure 8

Using the arc welding and cutting equipment requires

strict respect for safety conditions regarding electric

currents. Make sure that no metallic parts accessible

to the operators may come into direct or indirect

contact with a phase conductor or with the neutral

of the power grid.

All electrode holders and torches used must be in

good conditions. Do not coil the cables around your

body and never point the torchs to other people

(Fig. 9).

Figure 9

Make sure that no power cables from other ap-

pliances, control lines or phone cables are near the

generators.

Any other electric equipment in the welding or cutting

area must be in conformity with the corresponding

EMC regulation.

Caution: Access to the the working area

and near the welding/cutting operation

generators is forbidden to anyone wearing

pacemakers or other such electric devices.

At least once every 6 months make sure that all

electric appliances and accessories are well insulated.

Contact your supplier for more information on the

maintenance and repair of such equipment.

Warning: Never touch the welding cable or

the electrode and the piece which is being

welded at the same time.

ELECTRIC SYSTEM

Any intervention on electrical and electronic

equipment must be entrusted to qualified technicians

capable of performing such operations.

Prior to connecting your appliance to the power grid,

make sure that the counter, the overload and short-

circuit protection devices, the sockets, the plugs and

the electric system as a whole are compatible with

the maximum power of the appliance and its voltage

(please check the information on the plate) and in

conformity with the norms and regulations in force.

The ground single-phase or three-phase connection

(yellow/green cable) must be protected by a medium

or high-intensity differential-residual current device

(sensitivity between 1 and 30 mA).

If the cable is connected, the earth cable (when

present) must not be interrupted by the protection

device against electric shock. The switch, if present,

must be at “O”; the power cable, if not supplied,

must be of the harmonized type.

Ground all metal parts near the operator, using

cables that are thicker or as thick as the welding

cables.

The protection class of the appliance is IP22S, which

means it prevents:

- manual contact with internal parts in high tempe-

rature, which are moving or live;

- the introduction of solid bodies with more than 12

mm of diameter;

- protection against rain with maximum inclination

of 15°.

FIRE PREVENTION

The working area must be in conformity with safety

regulations. This means that fire extinguishers must

be installed, compatible with the type of fire which

may happen.

The ceiling, the floor and the doors must be non-

flammable. All combustible material must be moved

away from the workplace (Fig. 10). If this is not

possible, cover it with a fireproof cover.

Figure 10

Before you start welding or cutting, ventilate all areas

that are potentially flammable.

Do not use the equipment in places with significant

concentrations of dust, flammable gas or combusti-

ble liquid vapor.

The generator must be placed on solid, smooth floor,

and should never lean against walls.

Do not weld or cut containers filled with gasoline,

lubricant or other flammable substances.

EN-5

Under normal work conditions, the noise emitted by

a welding/cutting generator does not exceed 80 dBA;

should it be necessary to emit noise above 85 dBA,

the worker involved must be equipped with suitable

protections, such as helmet and ear plugs, and be

informed by suitable signaling.

FIRST AID

Each country specifies the minimum personal pro-

tection equipment that employers must provide their

first aid team with, for immediate help in the event of

electric shock, suffocation, burns of different types,

eye burns etc.

Beware of electric shock and electric burns:

the workplace may be dangerous; do not

attempt to help the patient if the power

source is still active. Cut off the appliance

from the power source and remove all po-

wer cables from the victim using a piece of

dry wood or any other insulating material.

ELECTROMAGNETIC COMPATIBILITY

Before installing your welder, carry out an inspection

of the surrounding area, observing the following

guidelines:

• Make sure that there are no other power sup-

ply cables, control lines, telephone leads or

other equipment near the unit.

• Make sure that there are no radio receivers,

television appliances, computers or other

control systems near the unit.

• People with pace-maker or hearing-prosthe-

sis should keep far from the power source.

! In particular cases special protection

measures may be required.

Interference can be reduced by following these sug-

gestions:

• If there is interference in the power source

line, an E.M.T. filter can be mounted between

the power supply and the power source;

• The output cables of the power source should

be not too uch long, kept together and con-

nected to ground;

• After the maintenance all the panels of the po-

wer source must be securely fastened in place.

Do not weld or cut near ventilation ducts, gas ducts

or any other installation which could accelerate the

spreading of a fire.

After concluding the welding or cutting operation,

always make sure that no incandescent or burning

material has been left in the area.

Make sure the earth connection is good; a defective

ground connection may result in an electric arc which

can become the cause of a fire.

PROTECTION GAS

Strictly follow all instructions of use and handling

provided by the gas supplier. In particular: the areas

of storage and use must be open and ventilated,

sufficiently away from the working area and from

sources of heat (< 50°C). Fix the cylinders, protect

them from impact and from any technical accident.

Make sure the cylinder and the pressure gauge corre-

spond to the gas required for the welding operation.

Never lubricate the cylinder taps and do not forget

to remove all gas from the same before connecting

the pressure gauge.

The protection gases must be dispensed at the

pressures recommended for the different welding/

cutting procedures.

Periodically inspect the ducts and rubber tubes to

make sure they are properly sealed. Never use

a source of flame/fire to detect gas leaks; use a

suitable detector or brush the suspected area with

soapy water.

Warning: Improper use of the gas, in par-

ticular in small spaces (cargo holds, tanks,

reservoirs, silos etc), will expose the user to

the following risks:

1. Suffocation or intoxication with gas and gassy

mixtures containing less than 20% of carbon

dioxide (these gases replace oxygen in the

air);

2. Fire and explosion with gassy mixtures con-

taining hydrogen (hydrogen is light and flam-

mable; it accumulates beneath ceilings or in

nooks, resulting in risk of fire and explosion).

NOISE

The safety prescriptions regarding workers’ pro-

tection against the risks derived from exposure to

noise are treated by European Directive 2003/10/

CE of 6 February 2003, which describes the need

to adopt measures to promote safety, hygiene and

good health in the workplace.

The noise emitted by the welding and cutting gene-

rators depends on the intensity of the welding/cutting

current, on the procedure used (MIG, pulsed MIG,

TIG etc), on the work environment (size of the area,

reverberation of the walls etc).

EN-6

PLASMA ARC AND BASIC PRINCIPLES

FOR THE PERFORMANCE OF PLASMA

CUTTING

• Plasma is a gas that is heated to an extremely

high temperature and ionised so that it beco-

mes a conductor of electricity.

• This cutting procedure utilises the plasma to

transfer the electric arc to the metal workpiece,

which is melted by the heatand then separated.

• The torch uses compressed air from a single

source, for both the plasma and cooling and

protective gas.

• The start of the cycle is determided by an arc,

called the pilot arc, which is struck between

the mobile electrode(negative polarity) and

the torch nozzle (positive polarity) due to the

short circuit between these two elements.

• When the torch is brought into direct contact

with the workpiece to be cut (connetcted to

the positive polarity of the power source) the

pilot arc is transfered between the electrode

and the workpiece itself thus striking a pla-

sma arc, also called cutting arc.

• The duration of the pilot arc is set in the fat-

cory at 3 seconds; if the transfer has not been

made within this time, the cycle is automati-

cally stopped except for the cooling air which

is kept on.

TECHNICAL INFORMATION

The data in the following table may differ

from the values on the data plates on the

rear panel of the generators.

The data may also vary according to the

torch that is gonna be used with the gene-

rator.

GENERAL INFORMATION

INSTALLATION

Be sure to locate the welder according

to the following guidelines.

• In areas, free from moisture and dust;

• Ambient temperature between 0° to 40°C;

• In areas, free from oil, steam and corrosive

gases;

• In areas, not subjected to abnormal vibration

or shock;

• In areas, not exposed to direct sunlight or rain;

• Make sure that obstacles do not prevent the

cooling air flow out of front and rear ope-

nings of the machine.

• Arrange an open space of at least 5m around

the machine.

• In the case the machine has to be moved,

always disconnect the plug from the outlet

and gather the cables and pipes so as not to

damage them.

Since the inhalation of welding fumes

can be harmful, ensure that the welding

area is effectively ventilated.

MAIN SUPPLY VOLTAGE REQUIREMENTS

Before you make any electrical connection,

check that supply voltage and frequency avai-

lable at site are those stated in the ratings la-

bel of your generator.

The main supply voltage should be within ±10% of

the rated main supply voltage. Too low a voltage

may cause poor welding performance. Too high a

supply voltage will cause components to overheat

and possibly fail. The welder Power Source must be:

• Correctly installed, if necessary, by a qualified

electrician;

• Correctly grounded (electrically) in accordan-

ce with local regulations;

• Connected to the correct size electric circuit.

LOCATION

PC 66 EVO

EN-7

In case the supply cable is not fitted with a plug,

connect a standardized plug (3P+T) to the supply

cable (in some models the supply cable is supplied

with plug).

To connect the plug to the supply cable, follow these

instructions:

• the brown (phase) wire must be connected to

the terminal identified by the letter L1

• the blue or grey wire must be connected to

the terminal identified by the letter L2

• the black or grey wire must be connected to

the terminal identified by the letter L3

• the yellow/green (ground) wire must be con-

nected to the terminal identified by the letter

PE or by the symbol .

In any case, the connection of the yellow/green wire

to the PE terminal must be done in order that in

the event of tearing of the power supply cable from

the plug, the yellow/green wire should be the last

one to be disconnected.

The outlet should be protected by the proper

protection fuses or automatic switches.

Notes:

• Periodically inspect supply cable for any

cracks or exposed wires. If it is not in good

conditions, have it repaired by a Service Cen-

tre.

• Do not pull violently the input power cable to

disconnect it from supply.

• Do not squash the supply cable with other ma-

chines, it could be damaged and cause electric

shock.

• Keep the supply cable away from heat sorces,

oils, solvents or sharp edges.

• In case you are using an extension cord, try to

keep it well straight and avoid its heating up.

SAFETY INSTRUCTIONS

For your safety, before connecting the power source

to the line, closely follow these instructions:

• An adequate switch must be inserted before

the mains outlet; this switch must be equip-

ped with time-delay fuses;

• The connection with ground must be made

with a plug compatible with the above men-

tioned socket;

• When working in a confined space, the power

source must be kept outside the welding area

and the ground cable should be fixed to the

workpiece. Never work in a damp or wet area,

in these conditions.

• Do not use damaged input or welding cables

• The welding torch should never be pointed at

the operator’s or at other persons’ body;

• The power source must never be operated

without its panels; this could cause serious

injury to the operator and could damage the

equipment.

CONNECTION TO GROUND CABLE

Connect the plug to the socket and the work cable

clamp to the piece to be cut or to the metallic

workbench. Take following precautions:

• Verify that there is a good electrical contact

particularly if insulated or oxidated coated

sheets are cut.

• Make ground connections as close as possi-

ble to the cutting area. The use of the metallic

structures which are not part of the workpie-

ce, such as the return cable of the cutting

current, may endanger the safety system and

give poor cutting results.

• Do not make a ground connection on the pie-

ce which has to be removed.

TORCH CONNECTION

Ensure unit is off and unpluged from the power

receptacle.

Figure 11

Supplied torch, manual or automatic, has a quick

connection system called “H Fit” . Correctly align the

“H Fit” pins and connect it to the connector on the

front panel of the unit by handscrewing the plastic

ring.

WARNING!: Before starting the cutting

operations verify that the parts are pro-

perly assembled by inspecting the head of

the torch as described on paragraph “Torch

Maintenance”.

TORCH CONSUMABLE PARTS MOUNTING

Position the torch with the outside protection nozzle

facing upward to prevent these parts from falling out

when the nozzle is removed.

WARNING: Wait the torch has completely

cooled before replacing torch parts to avoid

any damage to the torch head.

To change the torch consumable parts use the

following procedure:

1. Unscrew and remove the shield cup from the

Torch Head Assembly.

2. Remove the tip, gas distributor, and electrode.

3. Install the electrode, gas distributor, and tip.

Choose the correct consumable parts, refer

to the paragraph “Torch consumable parts

selection”.

4. Hand tighten the shield cup until it is seated

on the torch head. If resistance is felt when

installing the cup, check the threads before

proceeding.

5. if necessary, install also the spacer.

• The torch can be comfortably held in one

hand or steadied with two hands. Choose the

technique that feels most comfortable and

allows good control and movement. Position

the index finger or thumb to press the control

switch on the torch handle.

• For edge starts, hold the torch perpendicular

to the workpiece with the front of the tip on

the edge of the workpiece at the point where

the cut is to start - Fig. 16.

Figure 16

to supply primary power to the system.

GROUND CABLE

• Check for a solid ground cable connection to

the workpiece.

AUTOMATIC PURGE SYSTEM

• Place the ON/OFF switch to the ON position.

Activate the torch button to initiate 3s gas

purge (pre-flow) to remove any condensation

that may have accumulated in the torch and

leads while the system was shut down. When

the gas purge is complete, pilot arc will be

initiated. To cool torch handle or to further

remove condensation in the torch and leads

push the torch gas purge button (B) on the

front panel of the unit.

WARNING

Do not initiate pilot arc during adjustment.

CHECKING AIR QUALITY

• To check air quality, deactivate the torch (post-

flow) and place filter lens in front of the torch.

Any oil or moisture in the air will be visible

on the lens. DO NOT initiate pilot arc while

checking air quality.

OPERATION MODE SELECTION

• Select the desired operation mode with the

selection key (A) in the control panel.

AIR PRESSURE REGULATION

• Adjust the air pressure by pushing the air purge

button (B) and by acting on the air regulator (5).

• Adjust the correct air pressure for each ope-

ration mode.

• The display shows the adjusted air pressure in

bars. If air pressure is correctly adjusted the

LED “OK” is on. If the LEDs “Increase” or “De-

crease” are on, adjust again the air pressure

until these get off and LED “OK” lights on.

CUTTING CURRENT REGULATION

• Adjust the cutting current by acting on the ou-

tput current knob (2).

• With the torch in starting position, press the

control switch. After an initial gas purge (pre-

air), the pilot arc will come on and remain on

for 3 seconds until the cutting arc starts.

• Once on, the main arc remains on as long

as the control switch is held down, unless the

torch is withdrawn from the work or torch

motion is too slow. Keep moving while cut-

ting. Cut at a steady speed without pausing.

Maintain the cutting speed so that the arc lag

is about 30° behind the travel direction. Fig.

17. If the cutting arc is interrupted, and the

torch trigger is still pressed, the pilot arc co-

mes back on automatically for 3 seconds.

• To shut off the torch simply release the control

switch. When the switch is released a post-

flow will occur. If the torch trigger is pressed

during the post-flow, the pilot arc will restart.

• Hold the torch at a 45° angle with the

workpiece. Press the trigger to obtain a pilot

arc. Transfer the arc to the workpiece.

• Pull the torch back by keeping a 45° angle

with the workpiece and a certain distance

between the torch tip and the molten metal to

avoid consumable life reduction or damage

to the torch.

Changing the torch’s angle change the di-

mensions of the gouge.

• The gouge profile may vary in accordance with:

1. speed of the torch over the workpiece

2. the torch-to-work standoff distance

3. the angle of the torch to the workpiece

4. the adjusted current output.

• To increase width:

- Increase the standoff and/or the current.

- Decrease the speed and/or the angle.

• To decrease width:

- Increase the speed and/or the angle.

- Decrease the standoff and/or the current

• To increase depth:

- Decrease the speed and/or standoff.

- Increase the current and/or the angle.

• To decrease depth:

- Decrease the current and/or the angle.

- Increase the speed and/or standoff.

CUTTING WITH CNC

• Select the CNC mode with the selection key

(A) in the control panel.

• Follow indications at paragraph “Connection

of the machine to a CNC”

• Since the equipment with mechanized torch

can be used with different cutting tables, for the

operations in such configuration it is necessary

to consult the manufacturer’s instructions.

WARNING

Disconnect primary power at the source

and wait that the torch has cooled before

disassembling the torch or torch leads.

Frequently review the Important Safety

Precautions at the front of this Manual. Be

sure the operator is equipped with proper

gloves, clothing, eye and ear protection.

Make sure no part of the operator’s body

comes into contact with the work piece

while the torch is activated.

CAUTION

Sparks from the cutting process can cause

damage to coated, painted, and other sur-

faces such as glass, plastic and metal.

NOTE

Handle torch leads with care and protect

them from damage.

Figure 19

PIERCING WITH A HAND TORCH

Note: Recommended maximum piercing

capacity depends on the torch and on the

cutting current of the cutting unit. Refer to

the torch specification sheet provided with

the cuttig unit. If necessary to make a cut

on a metal sheet with a tickness more than

the maximum piercing capacity without

an edge start, make a hole ø 6mm at least

using an electric drill to start cutting.

• When piercing with a hand torch, tip the torch

slightly.

Figure 18

• Complete the pierce off the cutting line and

then continue the cut onto the line. Hold the

torch perpendicular to the workpiece after the

cut is complete. Fig.19

• Clean spatter and scale from the shield cup

and the tip as soon as possible.

GRATES CUTTING

• Select the automatic pilot arc mode with the

selection key (A) in the control panel.

MAINTENANCE

Maintenance can only be carried out on the unit if the

person in charge of this operation has the necessary

technical knowledge and the correct tools. If this is

not the case, contact your nearest service centre.

CAUTION!

Never access inside the machine (panel re-

moval) or touch the torch (disassemblage)

without having disconnected power plug.

Any inspection performed under voltage

inside the machine or inside the torch may

cause severe electric shocks caused by di-

rect contact with parts under voltage.

UNIT

Keep the cutting or gouging area and the area

around the machine clean and free of combustible

materials. No debris should be allowed to collect ,

this could obstruct air flow to the machine.

Inspect the unit every 3-4 months (depending on

how often the unit is used) and use compressed air

to remove any dust deposits.

CAUTION!

Only use dry compressed air for cleaning.

Do not point the jet of air at the electronic

circuits.

TORCH

Periodically, according to its use or to cutting faults

verify wear of the parts connected to plasma arc:

Shield Cup:

Unscrew manually from head of the torch. Clean

throughly abd replace if damaged (burns, distortions

or cracks). Verify integrity of superior metal sector

(actuator torch safety).

Tip:

Check wear of plasma arc hole and of inner and

outer surfaces. If the hole is widened compared to

its original width or if it is damaged, replace tip. If

surfaces are particularly oxidated clean them with

extra fine abrasive paper.

Air Distributor:

Verify the are no burns or cracks or that airflow holes

are not obstructed. If damaged, replace immediately.

Electrode:

Replace electrode when crater settling on emitting

surface is about 2mm.

WARNING!

• Before making any operation to the torch let

it cool at least all along the “postgas” period.

• Except for particular cases it is advisable to

replace electrode and tip AT THE SAME TIME.

• Respect assembly order of torch parts (reser-

ved compared to disassemblage).

• Be carefull that distributing is assembled pro-

perly.

• Reassemble shield cup screwing tightly and

manually.

• Never assemble shield cup without having

assembled electrode distributing ring and tip

beforehand.

• Timely and appropriate control procedures

on torch parts are essential for safety and

functionality of the cutting system.

TORCH BODY, HANDLE AND CABLE

• These parts usually need no particular main-

tenance with the exception of a periodic in-

spection and an accurate cleaning to be

made WITHOUT THE USE OF SOLVENTS.

• In case of damages to the insulation such as

breaks, cracks and burns or even a loosening

of electric coonductors, the torch CANNOT

BE USED FURTHER SINCE SAFETY CONDI-

TIONS HAVE NOT BEEN RESPECTED.

• IN THIS CASE, REPAIRING (EXTRAORDINA-

RY MAINTENANCE) CANNOT BE MADE ON

SITE BUT NEEDS TO BE DELEGATED TO A

SERVICE CENTER TO MAKE SPECIAL REST

TRIALS AFTER REPAIRING HAS BEEN EXECU-

TED.

In order to keep the torch and the cable efficient it

is necessary to follow these precautions:

• DO NOT touch torch and cable with warm

or hot parts.

• DO NOT strain the cable.

• DO NOT move the cable on sharp edges or

abrasive surfaces.

• gather the cable in regular coils if it is too

long.

• DO NOT step on the cable.

COMPRESSED AIR FILTER

The unit is also equipped with an air filter which

captures water and oil vapor.

Water contained in the glass can be drained through

a knob located on the bottom of the air filter. See

Purge Section.

recchio sia separato dall’impianto elettrico di

distribuzione dell’energia elettrica median-

te interdizione (con il termine interdizione si

intende un insieme di operazioni destinate a

separare ed a mantenere l’apparecchio fuori

tensione).

Un apparecchio elettrico elettronico non dovrà mai

essere utilizzato privo di pannelli e copertura, poiché

pericoloso per il personale operativo. Un simile

utilizzo potrebbe causare gravi danni all’ apparec-

chiatura stessa.

Questi generatori possono essere alimentati da

un gruppo elettrogeno; quest’ultimo dovrà tassa-

tivamente essere equipaggiato di motore diesel di

potenza superiore alla potenza richiesta dal gene-

ratore (fare riferimento alla tabella dati tecnici) e

con tensione di uscita di 400Vac +/- 10% - 3Ph

– 50/60Hz.
