INTRODUCTION
3.1
General
LAF 800 is a remote--controlled 3--phase welding power source 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 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 source 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 A2--A6 Process Controller (PEH)
instruction manual (order no. 0443 745 xxx).

OPERATION
5.1
Controls
The front panel contains:
1. Main switch, breaking the incoming mains voltage for the welding power source.
2. Indicating lamp (white), showing that the main switch is activated.
3. Indicating 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.
4. Pushbutton, for the resetting of automatic fuse FU2 for 42 V supply voltage.
5. Emergency 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).
5.2
Start--up
S
Connect the return cable to the work piece.
S
Set the main switch (1) to position “I“.
The white indicating lamp (2) goes on and the fan starts.
