1 SAFETY

1.1 Meaning of symbols

As used throughout this manual: Means Attention! Be Alert!

DANGER!
Means immediate hazards which, if not avoided, will result in immediate,

serious personal injury or loss of life.

WARNING!
Means potential hazards which could result in personal injury or loss of life.

CAUTION!
Means hazards which could result in minor personal injury.

WARNING!

Before use, read and understand the instruction manual
and follow all labels, employer´s safety practices and
Safety Data Sheets (SDSs).

1.2 Safety precautions

Users of ESAB equipment have the ultimate responsibility for ensuring that anyone who
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

1 SAFETY

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
○ Work on high voltage equipment may only be carried out by a qualified

electrician

○ Appropriate fire extinguishing equipment must be clearly marked and close at

hand

○ Lubrication and maintenance must not be carried out on the equipment during

operation

WARNING!

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

ELECTRIC SHOCK - Can kill

• Install and ground the unit in accordance with instruction manual.

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

• Insulate yourself from work and ground.

• Ensure your working position is safe

ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health

• Welders having pacemakers should consult their physician before welding.
EMF may interfere with some pacemakers.

• Exposure to EMF may have other health effects which are unknown.

• Welders should use the following procedures to minimize exposure to
EMF:

○ Route the electrode and work cables together on the same side of

your body. Secure them with tape when possible. Do not place your
body between the torch and work cables. Never coil the torch or work
cable around your body. Keep welding power source and cables as
far away from your body as possible.

○ Connect the work cable to the workpiece as close as possible to the

area being welded.

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.

0462 985 101

NOISE - Excessive noise can damage hearing

Protect your ears. Use earmuffs or other hearing protection.

1 SAFETY

MOVING PARTS - Can cause injuries

• Keep all doors, panels and covers closed and securely in place. Have only
qualified people remove covers for maintenance and troubleshooting as
necessary. Reinstall panels or covers and close doors when service is
finished and before starting engine.

• Stop engine before installing or connecting unit.

• Keep hands, hair, loose clothing and tools away from moving parts.

FIRE HAZARD

• Sparks (spatter) can cause fire. Make sure that there are no inflammable
materials nearby.

• Do not use on closed containers.

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

PROTECT YOURSELF AND OTHERS!

CAUTION!

This product is solely intended for arc welding.

WARNING!

Do not use the power source for thawing frozen pipes.

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.

NOTE!
Dispose of electronic equipment at the recycling

facility!

In observance of European Directive 2012/19/EC on
Waste Electrical and Electronic Equipment and its
implementation in accordance with national law,
electrical and/or electronic equipment that has reached
the end of its life must be disposed of at a recycling
facility.

As the person responsible for the equipment, it is your
responsibility to obtain information on approved
collection stations.

For further information contact the nearest ESAB dealer.

ESAB has an assortment of welding accessories and personal protection equipment
for purchase. For ordering information contact your local ESAB dealer or visit us on
our website.

2 INTRODUCTION

2 INTRODUCTION

Aristo 1000 is a welding power source intended for high productivity submerged arc welding

with direct current (DC) or alternating current(AC). The power source has many setting
options for those who want to optimise their welding process.

The welding power source is used together with control unit PEK. The welding process
parameters are regulated via the control unit.

The power source is part of ESAB's A2/A6system, which means that most of the
components from this system can be used with Aristo1000.

This includes components such as:

• Welding tractors

• Column and boom

• Welding heads

• Positioning equipment

• Joint tracking equipment

• Flux handling systems

ESAB accessories for the product can be found in the "ACCESSORIES" chapter of
this manual.

6 MAINTENANCE

6 MAINTENANCE

NOTE!

Regular maintenance is important for safe and reliable operation.

Only those persons who have appropriate electrical knowledge (authorised personnel) may
remove the safety plates to connect or carry out service, maintenance or repair work on
welding equipment.

CAUTION!

All warranty undertakings from the supplier cease to apply if the customer attempts
any work to rectify any faults in the product during the warranty period.

6.1 Welding power source

Check regularly that the welding power source is not clogged with dirt.

How often and which cleaning methods apply depend on:

• welding process

• operation time

• location

• surrounding environment

The power source should be regularly blown clean using dry compressed air at reduced
pressure, see the "CLEANING" appendix. This should be done more frequently in dirty
environments.

Clogged or blocked air inlets and outlets may result in overheating. Orderingnumber for dust
filter, see the "WEAR PARTS" appendix.

7 FAULT-TRACING

7 FAULT-TRACING

Try these recommended checks and inspections before sending for an authorized service
technician.

Type of fault Corrective action

No arc • Check that the mains voltage is switched on.

• Check that the welding and return cables are correctly
connected.

• Check that the correct current value is set.

• Check the mains power supply fuses.

The welding current is
interrupted during welding.

• Check whether the thermal cut-outs have tripped (a fault
code appears on the control module's panel).

• Check the mains power supply fuses.

The thermal cut-out trips
frequently.

• Check to see whether the dust filter is clogged.

• Make sure that you are not exceeding the rated data for
the welding power source (i.e. that the unit is not being
overloaded).

• Check that the welding power source is not clogged with
dirt.

• Check the ambient temperature.

Poor welding performance • Check that the welding current supply and return cables

are correctly connected.

• Check that the correct current value is set.

• Check that the correct filler material (wire and powder) is
used.
