○ relevant safety precautions

○ welding and cutting or other applicable operation of the equipment

2. The operator must ensure that:

○ no unauthorised person is stationed within the working area of the equipment when it

is started up

○ no-one is unprotected when the arc is struck or work is started with the equipment

3. The workplace must:

○ be suitable for the purpose

○ be free from drafts

4. Personal safety equipment:

○ Always wear recommended personal safety equipment, such as safety glasses,

flame-proof clothing, safety gloves

○ Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which could

become trapped or cause burns

5. General precautions:

○ Make sure the return cable is connected securely

WARNING!

Arc welding and cutting can be injurious to yourself and others. Take precautions

when welding and cutting. Ask for your employer's safety practices which should

be based on manufacturers' hazard data.

ELECTRIC SHOCK - Can kill

• Install and earth the unit in accordance with applicable standards

• Do not touch live electrical parts or electrodes with bare skin, wet gloves or

wet clothing

• Insulate yourself from earth and the workpiece

• Ensure your working stance is safe

FUMES AND GASES - Can be dangerous to health

• Keep your head out of the fumes

• Use ventilation, extraction at the arc, or both, to take fumes and gases away

from your breathing zone and the general area

ARC RAYS - Can injure eyes and burn skin

• Protect your eyes and body. Use the correct welding screen and filter lens and

wear protective clothing

• Protect bystanders with suitable screens or curtains

FIRE HAZARD

• Sparks (spatter) can cause fire. Make sure therefore that there are no

inflammable materials nearby

NOISE - Excessive noise can damage hearing

• Protect your ears. Use earmuffs or other hearing protection.

• Warn bystanders of the risk

MALFUNCTION - Call for expert assistance in the event of malfunction.

Read and understand the instruction manual before installing or operating.

PROTECT YOURSELF AND OTHERS!

WARNING!

Do not use the power source for thawing frozen pipes.

CAUTION!

Read and understand the instruction manual before

installing or operating.

CAUTION!

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 of

class A equipment in those locations, due to conducted

as well as radiated disturbances.

4 INSTALLATION

4.1 General

The installation must be carried out by a professional.

4.2 Lifting instructions

Lifting the power source by hand.

WARNING!

The power source weighs 50 kg (110 lbs).

WARNING!

Be two persons and lift the power

source by using the two handles.

Lifting the power source using hoist and strap.

WARNING!

Lift the power source by using the

eyebolt. Keep the power supply

as horizontal as possible.

WARNING!

Secure the equipment -

particularly if the ground is

uneven or sloping.

4.3 Location

Position the welding power source such that its cooling air inlets and outlets are not

obstructed. Make sure that no deposits or dust goes into the power source. Prevent impacts,

rubbing and exposure to dripping water, excessive heat sources or any unusual situations.

4.4 Mains supply

NOTE!

Mains supply requirements

This equipment complies with IEC 61000-3-12 provided that the short-circuit

power is greater than or equal to S

scmin

at the interface point between the user's

supply and the public system. It is the responsibility of the installer or user of the

equipment to ensure, by consultation with the distribution network operator if

necessary, that the equipment is connected only to a supply with a short-circuit

power greater than or equal to S

scmin

. Refer to the technical data in the

TECHNICAL DATA chapter.

CAUTION!

Make sure that the ON/OFF switch is set to OFF (0) before making any electrical

connections between the power source and the mains power supply.

Make sure that the welding power source is connected to the correct supply voltage and that

it is protected by the correct fuse rating. The mains distribution panel must comply with the

regulations in force in the country of use. The mains supply system must be of the industrial

type.

A protective earth connection must be made in accordance with regulations. The power

source must be correctly connected to earth to protect the operator. It is indispensable to

provide good earthing by means of the yellow-green lead in the power cable, to prevent

discharges due to accidental contacts with earthed objects. The chassis, which is conductive,

is electrically connected with the earth lead. If the equipment is not correct connected with

the earth lead it may cause electric shocks which are dangerous for the operator.

The power source works at mains voltages differing by 20% from the rated mains (400 V

rated, minimum voltage 320 V, maximum voltage 480 V).

Make sure that the Heliarc is correctly connected to earth to protect the operator. It is

indispensable to provide good earthing by means of the yellow-green lead in the power

cable, to prevent discharges due to accidental contacts with earthed objects.

The chassis, which is conductive, is electrically connected with the earth lead. If the

equipment is not correct connected with the earth lead it may cause electric shocks which

are dangerous for the operator.

The cooling unit must be connected to the power source with the special ILME multipole plug

supplied. Make sure that the power source is turned off and disconnected from the mains

power supply before making any electrical connections between the cooling unit and the

power source.

If the cooling unit is going to be connected to three phase mains voltage, replace the special

ILME 4-way plug with a three phase plug. Connect the supply wires to only two of the

contacts (black-brown) of the plug and the earth led (yellow/green) to the earth contact.
