TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK -- Can kill
SInstall and earth the welding unit in accordance with applicable standards.
SDo not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
SInsulate yourself from earth and the workpiece.
SEnsure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
SKeep your head out of the fumes.
SUse 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.
SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
SProtect bystanders with suitable screens or curtains.
FIRE HAZARD
SSparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
SProtect your ears. Use ear defenders or other hearing protection.
SWarn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
8 INTRODUCTION
LAF 800/1250/1600 are remote--controlled 3--phase welding power sources de-
signed 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.

The PC board (AP1) has two DIP switches (SW1 and SW2) which are preset on de-
livery. The settings are not to be changed.
When spare parts are supplied the settings of the DIP switches must be checked
(and set, if necessary) before fitting the PC board into the welding power source.
SDIP switch SW1
To make the communication with the A2--A6 Process Controller (PEH) work DIP
switch 1 (SW1) must be set.
SDIP switch SW2
DIP switch 2 (SW2) must be set in order to inform the A2--A6 process controller
(PEH) about the rating of the power source that is connected.
Setting of DIP switch SW1
SSet pole 6 to “OFF“ position and all other
poles to “ON“.
Setting of DIP switch SW2
LAF 800

10 OPERATION
10.1 Controls
The front panel contains:
1Main switch, breaking the incoming mains
voltage for the welding power source.
2Indicating lamp (white), showing that the main
switch is activated.
3Indicating lamp (yellow), showing that the
thermal protection has entered into action due
to overheating in the transformer. The lamp is
reset when the temperature has gone down to
an acceptable level.
4Pushbutton, for the resetting of automatic
fuse FU2 for 42 V supply voltage.
5Emergency pushbutton. When the button is
activated the main contactor in the power
source trips and the supply voltage for the
control box is broken. (The emergency button
on the control unit has the same function).
10.2 Start--up
SConnect the return cable to the work piece.
SSet the main switch (1) to position “I“.
The white indicating lamp (2) goes on and the fan starts.
SSet the welding parameters and start welding by way of the control box (see the
A2--A6 Process Controller 0443 745 001 instruction manual).
11 MAINTENANCE
11.1 Cleaning
SClean the welding power source as necessary.
Dry compressed air is recommended for the purpose.
WARNING!
Blocked air inlets or outlets will lead to overheating.
12 ORDERING OF SPARE PARTS
When ordering a spare part, please state the type and serial number of the machine
as well as number of the spare part, according to the spare parts list on page 23.
