Application class
Enclosure class IP23 IP 23
These welding power sources fulfil the requirements of IEC 60974--1
*) The minimum current during AC welding depends on the alloy used for the aluminium plates and
their surface cleanliness.
Duty cycle
The duty cycle refers to the time in per cent of a ten--minute period that you can weld at a certain load
without overloading the welding power source.
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.
