INTRODUCTION
2.1
General
Connection in parallel can be done with all sizes of the LAF welding power source.
The current outlet from each welding power source depends on its size, see below.
The mains connection is to be done in the
same way for
Master
and
Slave.
It is possible to use the so-called six-thyristor
effect by inverting the primary terminal of the
main transformer, see page 12.
Connection in Parallel of Welding Power Sources
of the Same Size
Connection in Parallel of Welding Power Sources
of Different Size
When the welding power sources are of different size
the smallest one is to be
Master
.
Current Outlet for Welding Power Sources of the Same Size
If the power sources are of the same size the current outlet will be evenly distributed.
Master 500 A
Slave 500 A
*1 Max = 1600 A
*2 500+500 = 1000 A
Current Outlet for Welding Power Sources of Different Sizes
If the Welding power sources are of different sizes the current outlet will be
procentually evenly distributed.
Master 500 A
Slave 300 A
*1 Max = 1000+600= 1600 A
*2 500+300 = 800 A
