Application class
Class of enclosures
IP 23
The welding power sources comply with the requirements set out in IEC 974--1
Cable areas acc. to Swedish regulations.
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.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
