ARC RAYS can burn eyes and skin. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld. D Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).
1-3. Additional Symbols For Installation, Operation, And Maintenance FIRE OR EXPLOSION hazard. D Do not install or place unit on, over, or near combustible surfaces. D Do not install unit near flammables. D Do not overload building wiring – be sure power supply system is properly sized, rated, and protected to handle this unit.
1-5. EMF Information Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields Welding current, as it flows through welding cables, will cause electro- magnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’...

LES RAYONS DE L’ARC peuvent pro- voquer des brûlures dans les yeux et sur la peau. Le rayonnement de l’arc du procédé de soudage génère des rayons visibles et invisibles intenses (ultraviolets et infrarouges) susceptibles de provoquer des brûlures dans les yeux et sur la peau. Des étincelles sont projetées pendant le soudage.
1-3. Dangers supplémentaires en relation avec l’installation, le fonctionnement et la maintenance Risque D’INCENDIE OU D’EXPLOSION.
