Enclosure class
*) 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 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
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.

INSTALLATION

The installation must be executed by a professional.
WARNING!
This product is intended for industrial use. In a domestic environment this product may cause radio
interference. It is the user's responsibility to take adequate precautions.
DTE 255 has mains voltage compensation, which means that +/− 10% variation in
the supply voltage produces only +/− 0.2% variation in the welding current.
To reduce the voltage drop resulting from the use of long welding cables, a cable
with a larger sectional area than the one indicated under Technical Data on page
can be used.
When the power source is started, the cooling fans work at a reduced rotation
speed, partly to reduce the amount of dirt that can be sucked in and partly to ensure
a lower noise level.
When the power source requires increased cooling, the fans work at a higher
rotation speed.
