ELECTROMAGNETIC COMPATIBILITY
ELECTROMAGNETIC fields may be hazardous.
EMU Class of machine according to TS EN 55011 is Group 2 Class A.
For detailed information refer to TS EN 60974-10.
While welding do not turn on/off the power switch.
This situation may cause voltage fluctuations in mains as well as shorten the
After turning on the power unit, you should wait approximately for 5-10
seconds for electrical stability of the machine and then
Welding machine has been designed according to related norms and rules. In addition, it
may cause safety problem for the devices affected from electromagnetic waves since it
may produce interfering electromagnetic waves for telecommunication devices
(telephone, radio, television) and safety equipments. To prevent and eliminate the effect
of these electromagnetic waves (interferences) produced by the machine, please read
below explanations carefully.
Welding machine has been intended to use in industrial fields. In case of using in living
spaces, to eliminate potential effects of electromagnetic waves it is necessary to use
specific precautions. User should certainly install and operate the machine as per the
instructions included in the user guide. In case any electromagnetic interference is
detected, user should take necessary precautions for this. If necessary, Kaynak Tekniği
Sanayi ve Ticaret A.Ş. will help to the user in this matter. No modifications should be
made on the machine without the written consent of Kaynak Tekniği Sanayi ve Ticaret
A.Ş.
Before the installation of the welding machine, user should check if there is any device in
the working area that may be affected due to electromagnetic waves. Some of these
devices are stated below:
1 - Lead wires, control cables and phone cables near the working area and machine,
2 - Radio and/or television receivers and transmitters, telecommunication devices,
3 - Computers or computer controlled devices,
4 - Safety and control equipments for industrial processes,
5 - Personal medical devices such as pacemakers and hearing aids,
Electromagnetic fields may interfere with some pacemakers. Therefore welders having
pacemakers should contact with their physicians before welding process.
6 - Calibration and measuring devices.
