Degree of protection<br />
Degree of protection for Kemppi machines is IP 23C. IP classification, degree of protection is shown as<br />
two figures: The first figure 2 indicates guarding protection during operation and handling for solid bodies<br />
with a diameter bigger than 12 mm. The second figure 3 indicates equipment is protected against water<br />
spray falling at up to 60 degrees from the vertical.<br />
Duty cycle<br />
Rated power of Kemppi welding machines is given as amperage based on the duty cycle percentage.<br />
The duty cycle has been tested and its performance characteristics are given for the temperature of<br />
+40°C. Therefore the actual duty cycle value can be higher in normal room temperature. Duty cycle 60%<br />
means 6 min arc time and 4 min rest time.<br />
Kemppi ICS (Isolated Cooling System)<br />
In Kemppi’s inverter power sources, a significant amount of heat is generated by the power<br />
semiconductors attached to the cooling elements, the transformer and the chokers. In order to guarantee<br />
reliability and optimal safety, the internal temperature of the machine has to be kept low.<br />
In Kemppi machines component heat output is moved to the air flowing through the equipment by means<br />
of a fan. Kemppi’s welding inverters use modern electronics to control the welding process, to guide the<br />
power source and to improve interface usability. Best of all, these components require no fan cooling.<br />
Welders work under dusty, dirty and damp conditions in which equipment is constantly being subjected<br />
to hard mechanical stress. In response to this challenge, Kemppi has developed the Isolated Cooling<br />
System ICS to improve the reliability of Kemppi welding equipment and to minimise maintenance.<br />
With ICS it is possible to maintain low component temperatures by directing the cooling air only<br />
through those power components that need cooling and by preventing the cooling air from reaching<br />
the electronic circuit cards. ICS switches the cooling fan on only if heat is generated in the power<br />
components.<br />
The end result is less dirt inside the machine, less maintenance.<br />
Kemppi MLS (Multi Logic System)<br />
The Multi Logic System (MLS) is Kemppi’s answer to growing need for high-quality welding user<br />
interfaces. With MLS it is possible to adapt the welding equipment to the welding job to the needs<br />
of the welding company. Exchangeable and clear panels allow the welder to input the current welding<br />
functions into the characteristics of the welding equipment.<br />
The same panels can be used with numerous power sources. The panel features have been selected<br />
carefully based on the needs of welding applications and customer companies worldwide.<br />
The MLS concept is based on flexibility and updatability. Modern digital technology is used to guide<br />
both the power source operations and the operating panels. The data transfer between the power source<br />
and the panel takes place in a fast digital channel.<br />
The visible user interface (displays, controls, switches) hides versatile Set Up functions that ensure panel<br />
functions comply with different welding needs without jeopardising usability. MLS makes it possible<br />
to solve future needs without having to replace the product. The characteristics of the present panel<br />
functions are changed and developed by adapting the software.<br />
