2SAFETY

In any arc welding or gouging operation, it is the responsibility of the user to observe certain safety rules

to ensure his personal safety and to protect those working near him. Read all safety articles relevant to

arc welding published by the WMA. Pay particular attention to any CAUTION or WARNING Notes in-

cluded in this manual. CAUTION indicates possible equipment damage. WARNING indicates possible

hazard to life.

1. Electrical

S Treat electricity with respect. Even the open circuit voltage of this equipment can be dangerous. Adjust-

ments to the torch or replacement of torch parts should be undertaken with the mains supply isolated from

the unit.

If damaged torch cables or torch components are found, the unit must be disconnected from the mains and

defective parts must be replaced using only Murex spare parts.

S Do not work on live circuits or cables. Disconnect the main power supply before checking the machine or

performing any maintenance operation.

S Be sure the case of the welding machine is properly connected to a good electrical earth.

S Have the wiring for the welding machine installed by a qualified electrician. All connections must be made

according to specifications in force and to general safety standards.

S Do not stand in water or on damp floors while using an arc welder or cutter. Do not use in the rain.

S Do not operate with worn or poorly connected cables. Inspect all cables frequently for insulation failure,

exposed wires and loose connections.

S Do not overload cables or continue to operate with overheating cables. Cables which are too small for the

current carried will overheat, causing rapid deterioration of the insulation.

S Pay attention that live parts of the torch do not touch any metal which is connected to the earth cable. Fix

an insulated hook to hang the torch on when it is not in use.

2. Ventilation

S Do not weld or cut on containers which have held combustible or flammable materials, or materials which

give off flammable or toxic vapours when heated, without proper cleaning.

S Locate the welding/cutting operation far enough from any vapour--type degreaser using trichlorethylene or

other chlorinated hydrocarbons as solvents. The ultraviolet light from the arc can decompose these va-

pours into toxic gases at a considerable distance from the arc, even though the concentration of the gases

is low enough to be undetectable by smell.

S Be sure to provide adequate ventilation for removal and dilution of fume and gases. Fume exhaust facilities

near the arc, or a ventilated helmet should be used when cutting in confined spaces or on toxic material.

3. Glare

S Never look at the arc without wearing eye protection.

Always use the proper protective clothing, filter glasses, and gloves. Be careful to avoid exposed skin

areas. Do not use cracked or defective helmets or shields.

S Never s trike an arc when there is someone near who is not protected from the strong light of the arc.

S Warn bystanders who are not aware of the dangers of ultraviolet light.

4. General

S Take care when lifting the unit.

S Ensure that cylinders are secured by chains.

S Locate the unit so that there is adequate air flow to the ventilation louvres.

S Always dress correctly to protect against glare, radiation and spatter.

5. Fire

S Ensure that the correct type of fire extinguisher is available in the welding area.

S Do not weld near flammable materials or liquids, in or near explosive atmospheres, or on pipes carrying

explosive gases.

6. Vehicle electrics

S When working on motor vehicles, remove the battery and any circuitry which may be damaged by the arc.

S Whilst welding be aware of the possibility of ’hidden wires’ behind panels or bulkheads.

The ON/OFF switch on this equipment does not isolate the unit from the mains electrical supply.

AC POWER IS PRESENT ON THE ON/OFF SWITCH TERMINALS.

The ON/OFF lamp is an indication that the supply is switched on and does not imply that the unit is isolated from the supply.

BEFORE REMOVING THE COVERS FOR MAINTENANCE, ISOLATE THE UNIT FROM THE MAINS ELECTRICAL

SUPPLY.

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

S Insulate yourself from earth and the workpiece.

S Ensure your working stance is safe.

FUMES AND GASES -- Can be dangerous to health

S Keep your head out of the fumes.

S Use ventilation, extraction at the arc, or both, to keep fumes and gases from your breathing zone and

the general area.

ARC RAYS -- Can injure eyes and burn skin.

S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

S Protect bystanders with suitable screens or curtains.

FIRE HAZARD

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

S Protect your ears. Use ear defenders or other hearing protection.

S Warn bystanders of the risk.

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

PROTECT YOURSELF AND OTHERS!

WARNING

This product is intended for industrial use. In a domestic environment this prod -

uct may cause radio interference. It is the users responsibility to take adequate

precautions.

This welding equipment has been designed, manufactured and tested to the highest standards to ensure long

and trouble free life. However, regular maintenance is an essential part of keeping the machine operating in a

reliable and safe manner and your attention is drawn to any maintenance instructions that are contained in this

manual.

In general all welding equipment should be thoroughly inspected, tested and serviced at least annually. More

frequent checking will be required when the equipment is heavily used.

Wear and tear, particularly in electro-- mechanical and moving components, are gradual processes. Caught in

time, repair costs are small and the benefits in performance reliability and safety are significant. Left alone they

can put the equipment, and you, at risk.

Have this equipment regularly inspected and maintained by an approved service centre.

3 INTRODUCTION

LAF 1000/ 1000M are r emote--controlled 3--phase welding power sources designed

for high--efficiency mechanical gas metal arc welding (MIG/MAG) or sub arc welding

(SAW). It is always to be used in combination with ESAB‘s control box

A2--A6 Process Controller (PEH).

LAF is fan--cooled and monitored by a thermal overload protection. When the protec-

tion enters into action a yellow indicating lamp on the front panel goes on and is

reset automatically as soon as the temperature has gone down to an acceptable

level.

The welding power sources and the control unit are linked together over a 2--wire

bus enabling precision control of the welding process.

All welding parameter settings for the power source can be made by the operator on

the front panel of the control unit. The operation of the power source is completely

controlled and monitored by this unit. Even the start and stop qualities can be set by

way of the control unit. The preset welding current parameters can also be moni-

tored in the course of welding.

For more detailed information regarding the settings and the working mode of the

welding power source, please refer to the A2--A6 Process Controller (PEH) instruc-

tion manual.
