ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE 

SERIOUS INJURY OR DEATH.  KEEP CHILDREN AWAY.  PACEMAKER WEARERS SHOULD 

CONSULT WITH THEIR DOCTOR 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.
