ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE 
SERIOUS INJURIES OR DEATH.  KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD 
CONSULT WITH THEIR DOCTORS BEFORE OPERATING.  
 

Read and understand the following safety highlights. For additional safety information, it is strongly recommended  
That you purchase a copy of “ Safety in Welding & Cutting – ANSI Standard Z49.1 ” from the American Welding  
Society, P.O. Box 351040, Miami, Florida 33135 or CSA Standard W117.2-

1974. A Free copy of “Arc Welding  

Safety ” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 
44117-1199.  

 

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES 
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.  

 

     

  

 

 

  

1.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current 

          creates EMF fields around welding cables and welding machines. 
    
   1.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult with their physician 
          before welding. 
    
   1.c. Exposure to EMF fields in welding may have other health effects which are now not known.  
 
   1.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit: 
        
          1.d.1. Route the electrode and work cables together. Secure them with tape when possible. 
 
          1.d.2. Never coil the electrode lead around your body.  
  
          1.d.3. Do not place your body between the electrode and work cables. If  the electrode cable is on your right side, 
                    the work cable should also be on your right side. 
 
          1.d.4. Connect the work cable to the workpiece as close as possible to the area being welded. 
 
          1.d.5. Do not work next to welding power source.  
 
 

           
 
      
 

                                                                                

 
 
 
 
 
 
 

 ELECTRIC AND MAGNETIC FIELDS 
 May be dangerous
