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 ARE

 

 

 

PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
