Electromagnetic Compatibility (EMC) 

01/11 

This machine has been designed in accordance with all relevant directives and standards. However, it may still generate 
electromagnetic disturbances that can affect other systems like telecommunications (telephone, radio, and television) or 
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand this 
section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine. 
 

This machine has been designed to operate in an industrial area.  To operate in a domestic area it is necessary 
to observe particular precautions to eliminate possible electromagnetic disturbances. The operator must install 
and operate this equipment as described in this manual.  If any electromagnetic disturbances are detected the 
operator must put in place corrective actions to eliminate these disturbances, if necessary with assistance from 

Lincoln Electric. 
 
Before installing the machine, the operator must check the work area for any devices that may malfunction because of 
electromagnetic disturbances. Consider the following. 

  Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and the machine. 

  Radio and/or television transmitters and receivers. Computers or computer controlled equipment. 

  Safety and control equipment for industrial processes. Equipment for calibration and measurement. 

  Personal medical devices like pacemakers and hearing aids. 

  Check the electromagnetic immunity for equipment operating in or near the work area. The operator must be sure that 

all equipment in the area is compatible. This may require additional protection measures. 

  The dimensions of the work area to consider will depend on the construction of the area and other activities that are 

taking place. 

 
Consider the following guidelines to reduce electromagnetic emissions from the machine. 

  Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take 

additional precautions such as filtering the input supply. 

  The output cables should be as short as possible and positioned together as close as possible to each other. If possible 

connect the work piece to ground in order to reduce the electromagnetic emissions. The operator must check that 
connecting the work piece to ground does not cause problems or unsafe operating conditions for personnel and 
equipment. 

  Shielding of cables in the work area can reduce electromagnetic emissions. This may be necessary for special 

applications. 

 

 WARNING 

EMC classification of this product is class A in accordance with electromagnetic compatibility standard EN 60974-10 which 
means that the product is designed to be used in an industrial environment only. 
 

 WARNING 

The Class A equipment is not intended for use in residential locations where the electrical power is provided by the public 
low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility in those locations, 
due to conducted as well as radiated disturbances.
