Application classefication

These welding power sources conform to the requirements of

IEC 974--1.

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 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.
