Duty cycle
The duty cycle refers to the time as a percentage of a ten--minute period that you can weld at a cer-
tain load without overloading.
Enclosure class
The
IP
code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked
IP23
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.
WIRING DIAGRAM
The power source consists of a number of function modules, which are described in the
component descriptions on the following pages. Wire numbers and component names in
the wiring diagrams show to which module each component belongs.
Wires/cables within modules
are marked 100 -- 6999.
Circuit boards within each module
have names such as 20AP1 -- 20AP99.
15 = module association, 1--69
AP = circuit board
1
= individual identification number, 0--99
Components within modules
-- are named in a similar way.
