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 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 instruction manual for either the
A2 − A6 Process Controller or the A2 Welding Control Unit.

Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP 23 is designed for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
