works on or near the equipment observes all the relevant safety precautions. Safety
precautions must meet the requirements that apply to this type of equipment. The following
recommendations should be observed in addition to the standard regulations that apply to
the workplace.
All work must be carried out by trained personnel well-acquainted with the operation of the
equipment. Incorrect operation of the equipment may lead to hazardous situations which can
result in injury to the operator and damage to the equipment.
1. Anyone who uses the equipment must be familiar with:
○ its operation
○ location of emergency stops
○ its function
○ 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

1 SAFETY
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.
0463 369 001
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.

4.4 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
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
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).

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.

4 INSTALLATION
Connect the cooling unit to the power source
1. Remove the screws (1), the safety bolt (2) and the door panel (3).
2. Remove the plastic cap at the rear of the trolley chassi.
3. Pull the cooling unit input cable through the hole at the rear of the trolley chassi.
4. Fasten the input cable with the screws (4).
The Heliarc 353i AC/DC is already equipped with a connector to connect the cooling unit. To
start the cooling unit it is necessary to switch on both the power source and the cooling unit.
Hydraulic connection
Connect the water delivery pipe of the torch to water output coupling on the cooling unit.
Connect the water return pipe of the torch to the water input coupling on the cooling unit.
