S its operation
S location of emergency stops
S its function
S relevant safety precautions
S welding
2. The operator must ensure that:
S no unauthorised person is stationed within the working area of the equipment when it is
started up.
S no−one is unprotected when the arc is struck
3. The workplace must:
S be suitable for the purpose
S be free from draughts
4. Personal safety equipment
S Always wear recommended personal safety equipment, such as safety glasses, flame−proof
clothing, safety gloves.
S Do not wear loose−fitting items, such as scarves, bracelets, rings, etc., which could become
trapped or cause burns.
5. General precautions
S Make sure the return cable is connected securely.
S Work on high voltage equipment may only be carried out by a qualified electrician.
S Appropriate fire extinquishing equipment must be clearly marked and close at hand.
S Lubrication and maintenance must not be carried out on the equipment during operation.

WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK − Can kill
S Install and earth the welding unit in accordance with applicable standards.
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 take fumes and gases away 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.
NOISE − Excessive noise can damage hearing
S Protect your ears. Use earmuffs 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 product may cause radio interference. It is the users responsibility to take adequate

2 INTRODUCTION
2.1 General
LAF 1000/ 1000M are remote−controlled 3−phase welding power sources designed
for high−efficiency mechanical gas metal arc welding (MIG/MAG) or sub arc welding
(SAW). They are always to be used in combination with ESAB‘s control box
A2−A6 Process Controller (PEH) or A2 Welding Control Unit (PEI).
LAF is fan−cooled and monitored by a thermal overload protection. When the protection 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 monitored 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 instruction manual for either the
A2−A6 Process Controller or the A2 Welding Control Unit.
